oldurkey: Yes, I've noticed it too! (I think) Around the 1:35 mark, Bill sings "And 'shis' house just. ain't no home" Sounds like he wanted to sing "And she's always gone too long" instead. What a memorable song though.
I picked up on a mistake the very first time I heard this song (which I love) in 1972. To this day, I've not heard it mentioned by anyone. There's a slip-up in the words. Anyone know what I'm referring to?
