Yes, I understand Chiasmus. But only in that section. You state above “a song which is itself entirely a palindrome”!

Oh, and to add to your list of facts, Abba was the first musical guest to lip sync on “Saturday Night Live.”
(There’s a Fact of the Day on this in the library, but the comments, they won’t let me link….)

“Son I am able she said, though you scare me. Watch, said I, beloved, I said, watch me scare you though. Said she, able am I, Son.” is a palindrome which uses words as units instead of letters. Speaking in a literary sense, this configuration of wording is called chiasmus.

The song does include several letter-for-letter palindromes: “Man o nam” and the classic palindrome, “Egad, a base tone denotes a bad age.”

Either way, Giants write more interesting songs than ABBA.

I, man, am regal, a German am I.
Never odd or even.
If I had a Hi-Fi.
Madam, I’m Adam.
Too hot to hoot.
No lemons, no melon.
Too bad I aid a boot.
