Now this is the blues:
There was a white man had the blues
Thought it was nothing to worry about
Now you lay down at night
You roll from one side of the bed to the other all night long
Ya can't sleep, what's the matter? The blues has gotcha.

Ya get up you sit on the side of the bed in the mornin'
May have a sister a mother a brother an' a father around
But you don't want no talk out of 'em
What's the matter? The blues has gotcha.

When you go in put your feet under the table look down at ya plate
got everything you wanna eat
But ya shake ya head you get up you say
"Lord I can't eat I can't sleep"
What’s the matter? The blues has gotcha.

Why not talk to ya? Tell what you gotta tell it

Well, good morning blues, blues how do you do
Well, good morning blues, blues how do you do
I'm doing all right, good morning how are you.

Leadbelly, Huddie Ledbetter

I'm familiar with "what you heard are not the lyrics". My youth saw the Supreme Court exorcise the devil rock 'n roll with the decision that the lyrics to "Louie, Louie" were "unintelligible at any speed". Case closed. Let the music play on.

When you first mishear, the brain remembers, so you'll mishear again and again. Except when what you think you heard doesn't make sense to you, so you go looking for the correct text/lyrics to find out.

Sam L., I heard Eric Clapton's "Layla" as "Hey, Love" for some time b4 seeing the title. I still like my lyrics & title better, but Clapton wouldn't share credit! Go figure!
