Willie Nelson is one of the world’s most accomplished musicians—and not just in the country music world. Nelson’s talents transcend genre, and go far beyond music. Here are 10 things you might not know about the legendary outlaw country singer, who turns 86 years old today.

1. He wrote his first song at the age of seven.

While other kids were still struggling to keep inside the lines of their coloring books, Nelson was composing music. He recalled the experience of his songwriting debut to Rolling Stone in 2004: “Back when we used to take music lessons from our grandmother, we'd go through lessons, and if we'd get the lesson right that day she'd take a gold star—a little star, about the size of your finger, with glue on one side—and she'd stick it on the sheet of music, which meant you'd done well. So I wrote this song with the line ‘They took a gold star away from me when you left me for another, long ago.’ I'd never been left by anybody, so it was kind of funny.”

2. He used to be a Bible salesman.

Before he became a full-time musician in the mid-1950s, Nelson worked as a cotton picker (a gig he began as a child, working alongside his grandmother), disc jockey, and a Bible salesman.

3. He ran into a burning house (to save his pot).

While living in Nashville, Nelson arrived home one evening to discover that his house was burning to the ground. “By the time I got there, it was burning real good,” he told People in 1980. “But I had this pound of Colombian grass inside. I wasn't being brave running in there to get my dope—I was trying to keep the firemen from finding it and turning me over to the police.” One-hundred tapes of yet-to-be-recorded songs weren't as lucky as Nelson's stash; they were lost in the fire.

4. He retired in 1972. (Spoiler: It didn't last.)

In 1972, Nelson paid $14,000 to buy out his contract so that he could retire to Austin, Texas. But his withdrawal from the music business didn’t last long. Especially considering how vibrant the music scene was happening all around him in Austin. Within a year, he was back on the charts with the album Shotgun Willie. By the mid-1970s he scored some of his biggest hits with a trio of albums: Red Headed Stranger, The Sound in Your Mind, and The Troublemaker.

5. He has been playing the same guitar for 50 years.

Nelson has been playing Trigger, his beloved guitar (which he named after Roy Rogers’ horse), since 1969. “I’ve got to take good care of Trigger,” Nelson told Uncut Magazine in 2014. “He’s had a couple of problems. We’ve had to go in and do some work on the inside, build up the woodwork in there a little bit over the years. But Trigger’s holding up pretty good.”

6. He recorded The IRS Tapes to pay off his tax debt.

In 1990, the IRS raided Nelson’s house and seized his assets (everything except Trigger) for non-payment of taxes. The $32 million bill, one of the largest in IRS history, was eventually negotiated down and settled in a creative way: Nelson would record a new album with the IRS receiving at least 15 cents of every dollar made. The result was the limited-edition The IRS Tapes: Who’ll Buy My Memories, which sold for $19.95 on cassette or CD and was purchased by dialing 1-800-IRS-TAPE.

7. He wrote "On the Road Again" on a barf bag.

Nelson’s 1980 hit, “On The Road Again,” was written aboard an airplane—on a barf bag. “I was on an aeroplane with Sydney Pollack and Jerry Schatzberg, who was the director of the movie Honeysuckle Rose,” Nelson told Uncut in 2014. “They were looking for songs for the movie and they started asking me if I had any ideas. I said, ‘I don’t know, what do you want the song to say?’ I think Sydney said, ‘Can it be something about being on the road?’ It just started to click in my head. I said, ‘You mean like, ‘On the road again, I can’t wait to get on the road again?’ They said, ‘That’s great. What’s the melody?’ I said, ‘I don’t know yet.’”

8. He performed "Up Against the Wall, Redneck Mother" with Rosalynn Carter.

Former President Jimmy Carter has never made a secret of his admiration of Willie Nelson. And the two have shared a long friendship. On September 13, 1980, Nelson performed for Carter and guests at the White House—which included a duet of Ray Wylie Hubbard’s “Up Against the Wall, Redneck Mother” with then-First Lady Rosalynn Carter. (On various occasions, Nelson has recounted how he later made his way onto the roof of the White House and smoked a joint.) In 2012, the former President got his own chance to share the stage with the legendary musician when the two performed “Amazing Grace” together in Atlanta.

9. His album Stardust spent years on the country music charts.

The 1978 album Stardust, which features Nelson-ized renditions of pop standards like "Georgia on My Mind" and "Unchained Melody" spent two years on the Billboard 200, and a total of 540 weeks (a total of more than 10 years) on various country music charts.

10. He's a pot-repreneur.

Nelson has hardly made a secret of regular marijuana use, or his support for its legalization. (His rap sheet of pot-related arrests certainly backs up those claims.) As more and more states are legalizing the once-outlawed weed, Nelson has put his expertise on the topic to good use, and launched his very own brand of pot: Willie’s Reserve.
