What makes that happen? They weren't "ear worms" as I understand those. To me an ear worm can't be easily gotten rid of except to sing it to someone and thereby passing it on.
And then there are the misheard lyrics. Most are pretty well known like Hendrix "'scuse me while I kiss this guy" or CCR's "there's a bathroom on the right". There are more obscure ones like the Association's "Windy". The real lyric is "Who's sweepin' down to capture a moment" but sometimes heard as, " Who's creepin' out to capture a Mormon."
Or The Allman Brothers "Whippin Post" heard as "Sometimes I feel, sometimes I feel, Like I been tied to the fishin' pole".
David Bowie's Space Oddity, "And the papers want to know who shot you where." " Clown control to Mao Tse Tung".
Fleetwood Mac's Landslide, "I took my love, and I took it down", or was it " I took my love and I milked a cow". Or Bill Clinton's favorite, "Don't stop thinkin' about tomorrow" to "Don't stop thinkin' about your mama."
Back to Simon and Garfunkel. "And here's to you Mrs. Robinson, She's a slut, that's more than you should know."
There must be hundreds or thousands of these that are heard by everyone. After all it is better to make something up than just mumble your way through lyrics you just don't know. And what about all the foreign languages? They must have these, too! Imagine a group like Led Zeppelin writing lyrics in Gaelic or Swahili.
Or maybe the Three Stooges "Swingin' The Alphabet". Just a musical interlude for your listening pleasure. Really!
Yes, it's true I sometimes slip back into something less mature
