In Hitchin a ride:
I heard: "I meant it Salmonella poison"
While it was " Fermented Salmonella poison"
I heard: "Tonight I "meat or crow""
While it was "Tonight I'm eating crow"
In On the Wagon:
I heard: "For input twice the size of my one-aged mind"
While it was: "For input twice the size of my one inch mind"
I heard: "Well today I say sweet things about tomorrow"
While it was: "Well today I say sweet things, but tomorrow"
In Disappearing Boy:
I heard: "I'm looking, sharing my own joy"
While it was: "I vanished from all your joy"
(I had no idea what he was saying there so I made up something )
I heard: "Or am I climbing on the stairs"
When it was: "Or am I playing on the stairs"
In Holiday:
Just before the "representative from California" part:
I heard: "Take four"
While it was: "Three, Four"
In I Fought the Law
I heard: "Bacon rocks in the hot sun"
While it was: "Breaking rocks in the hot sun"
There are probably even more (I've posted here quite many already), but sometimes you don't know that you've been singing the song with incorrect lyrics for many years before you check it up.
