One of the last remaining Beatles mysteries has finally been solved. For decades, no one knew for certain which Beatle wrote the 1965 song “In My Life”—Paul McCartney claimed to have written the music, but John Lennon said that McCartney only wrote part of it.
Now, academics have used a statistical method to get to the bottom of the song’s origin, and the numbers show that neither musician remembered it correctly, as NPR reports. According to a paper recently presented at a major statistics conference, Lennon wrote the entire song himself.
Lennon and McCartney shared a joint credit for all of the songs they wrote, regardless of the division of work. This reportedly stems back to an agreement they made as teenagers. Jason Brown, a mathematics professor at Canada's Dalhousie University, spent at least 10 years trying to crack the puzzle of who actually wrote “In My Life.”
Even though the two artists undoubtedly rubbed off on each other artistically during their years together, the two musicians still had their preferences, which can be charted and quantified. Brown and his co-authors—a mathematician and an engineering professor—analyzed individual notes, chords, and other components in dozens of Beatles songs to determine how often they appear in the Lennon-McCartney song catalog, identifying 149 distinct musical transitions in the Beatles oeuvre. Those stylistic choices are unique to the individual songwriter.
“When you do the math by counting the little bits that are unique to the people, the probability that McCartney wrote ["In My Life"] was .018—that's essentially zero,” Stanford mathematician Keith Devlin, who was not involved in the study, explained to NPR. “In other words, this is pretty well definitive. Lennon wrote the music.”
While some might be skeptical of reducing a creative process to numbers, Devlin said this method is “much more reliable than people’s recollections,” especially given the “incredibly altered mental state” that The Beatles found themselves in throughout much of the ’60s. And this isn't the first analysis of its kind. Another study in 2014 [PDF] determined that lyrics and algorithms could also be used to determine whether a song was written by McCartney or Lennon.
This wasn't Brown's first investigation into The Beatles' songwriting process, either. Back in 2008, he used sound-wave analysis to figure out how The Beatles created the opening chord of “A Hard Day’s Night,” hypothesizing that it was a combination of guitar, bass, and piano.
Lennon once said in an interview that he was inspired to write “In My Life” after a journalist suggested he model more songs after his own life experiences. Lennon later said that he considered the song to be his first major, meaningful piece of work, adding that, “Up until then, it had all been glib and throwaway.”

Maybe it’s Max Weinberg’s fault. In the opening seconds of Bruce Springsteen’s 1984 single “Born in the U.S.A.,” Weinberg, the drummer for Springsteen’s E Street Band, laid down some ferocious snare hits, invoking cannon blasts and fireworks and all the national pride associated with those sounds. The track explodes before Springsteen even utters a single word, casting red, white, and blue filters on a set of lyrics imbued with many more colors and layers.
Casual radio listeners in 1984 were bound to hear “Born in the U.S.A.” as an ode to patriotism, and the perfect soundtrack for President Reagan’s “Morning In America” campaign. Reagan himself invoked Springsteen’s name during an August 1984 campaign stop in New Jersey. “America’s future rests in a thousand dreams inside your hearts,” Reagan said. “It rests in the message of hope in songs so many young Americans admire: New Jersey’s own Bruce Springsteen.”
From a distance, Springsteen looked the part of the jingoistic flag-waver. The scruffy, sinewy rocker pictured on the cover of 1975’s star-making Born to Run album had evolved into a musclebound, headband-wearing, stadium-wrecking legend-in-the-making. When he sang, “I was born in the U.S.A.,” it sounded like a declaration of pride and faith.
But “Born in the U.S.A.,” the title track off Springsteen’s blockbuster seventh album, wasn't the nationalistic singalong many people thought it was. In his 2016 memoir Born to Run, Springsteen rightfully called it “a protest song," and the angry tone ought to be clear from the opening line: “Born down in a dead man’s town / The first kick I took was when I hit the ground.”
The song's lyrics tell of a local loser who’s railroaded into military service during the Vietnam War, scarred by his experiences in Southeast Asia, and completely forgotten about by his country when he returns home. Springsteen's protagonist can’t find work or shake the image of the brother he lost in Khe Sanh. Ten years after the war, he’s got nothing left except a claim to his birthplace. And he’s not sure what that’s worth.
Springsteen wrote “Born in the U.S.A.” after reading Born on the Fourth of July, Vietnam veteran and antiwar activist Ron Kovic's memoir (which Oliver Stone later adapted into an Oscar-winning film starring Tom Cruise). Springsteen purchased the book at a gas station in Arizona in 1978 and was moved by Kovic’s story of a young man who enlists in the Marines and returns from Vietnam in a wheelchair, paralyzed from the waist down.
Not long after Springsteen read the book, he happened to meet Kovic by the pool at Hollywood’s Sunset Marquis hotel. They struck up a friendship, and Springsteen wound up staging an August 1981 benefit concert for the fledgling Vietnam Veterans of America.

In writing “Born in the U.S.A.,” Springsteen was also motivated by survivor’s guilt—or perhaps more correctly, avoider’s guilt. By his own admission, Springsteen was a “stone-cold draft dodger.” When he was called up by his local draft board in the ‘60s, Springsteen used all the tricks in the book to avoid being selected. According to Rolling Stone, Springsteen's "efforts to convince a Newark, New Jersey, selective service board of his abject unsuitability for combat in Vietnam apparently extended to claiming he was both gay and tripping on LSD, but none of it was necessary." In the end, Springsteen was dismissed not for any of those made-up reasons, but because a concussion he had suffered in a motorcycle accident resulted in him failing his physical. He was classified 4F, or unfit for service.
“As I grew older, I sometimes wondered who went in my place,” Springsteen wrote in Born to Run. “Somebody did.” In fact, Springsteen knew some people who lost their lives in Vietnam, including Bart Haynes, the drummer in his first band. During concerts in the ‘80s, Springsteen would often share the memory of Haynes coming to his house and telling him he’d enlisted, and that he was going to Vietnam, a country he couldn’t find on the map.
Springsteen began writing what would become “Born In the U.S.A.” while compiling material for 1982’s stark acoustic album Nebraska. The original title was “Vietnam,” and an early version of the lyrics have the protagonist’s girlfriend ditching him for a rock singer. At some point in the process, Springsteen picked up a screenplay that Paul Schrader, the writer behind Taxi Driver, had sent him. It was called Born in the U.S.A., and while it was about a Cleveland bar band, not the plight of Vietnam vets, Springsteen recognized the power of the title.
Another influence was the 1979 book Sideshow: Kissinger, Nixon and the Destruction of Cambodia. As Brian Hiatt reveals in his 2019 book Bruce Springsteen: The Stories Behind the Songs, one draft of “Born In the U.S.A.” advocates rough justice for Nixon, suggesting we should “cut off his balls.” That line didn’t survive the editing process, but Springsteen’s anger certainly did.

There are conflicting stories about how “Born In the U.S.A.” became such a colossal-sounding song in the studio. E Street keyboardist Roy Bittan credits himself with latching onto a six-note melody Springsteen sang when sharing the song with the band for the first time. Those six notes became the central riff of the song. Having listened to Springsteen’s lyrics, Bittan aimed for a “Southeast Asian sort of synthesized, strange sound” on his Yamaha CS-80 synthesizer. It sounded even more impactful once Weinberg began slapping that snare behind it.
In Weinberg’s version of events, the floor-shaking final version of “Born In the U.S.A.” grew out of a sparser “country trio” arrangement. When Springsteen switched up and began strumming his guitar in a style reminiscent of The Rolling Stones’s "Street Fighting Man," Weinberg drummed along, and soon the whole band followed.
Regardless of how it transpired, Springsteen was definitely down with “Born In the U.S.A.” being a rager. In the studio, engineer Toby Scott ran Weinberg’s drums through a broken reverb plate, putting a custom spin on the “gated reverb“ sound popularized by Phil Collins earlier in the ‘80s. Weinberg is well-deserving of his nickname, “Mighty Max,” but technology helped to give his thunderous playing that extra oomph it needed.
The version heard on the album is an early live take, with some additional jamming removed to keep the runtime under five minutes. Springsteen has subsequently done more somber acoustic versions of “Born In the U.S.A,” but they lack the juxtapositions that make the studio version so compelling—and confusing for some listeners.
“On the album, ‘Born In the U.S.A.’ was in its most powerful presentation,” Springsteen wrote in Born to Run. “If I’d tried to undercut or change the music, I believe I would’ve had a record that would’ve been more easily understood but not as satisfying.”
“Born In the U.S.A.” ultimately is a patriotic song—just not the kind President Reagan was looking for. Springsteen’s traumatized, unemployed protagonist wants to believe that being American means something. Sex Pistols frontman Johnny Rotten once said that he didn’t write the incendiary 1977 punk single “God Save the Queen” because he hates the English—but rather because he loves them and thinks they deserve better. “Born In the U.S.A.” is the same type of song, even if some people will never understand it.
“Records are often auditory Rorschach tests,” Springsteen wrote in his memoir. “We hear what we want to hear.”
