[Slowhand] Sweet Home Chicago

[Jon Maclean]

With all the positive feedback for the new CD/DVD combo, I thought I'd raise 
one small issue.
Eric does a fabulous version of Sweet Home Chicago, but if you listen 
carefully to the lyrics they differ from Johnson's original on the Complete 
RJ box set (2 CD on Columbia).
Whereas Johnson's mathematics remain true, Clapton sings "two and four is 
eight", which is obviously nonsensical. Clapton is generally very particular 
in his attention to detail, so his version must be based on something else. 
I seem to remember his live versions in 94 also included mathematical 
errors. Maybe he just keeps forgetting the right lyric!
It's hardly a ground-breaking issue, but I'm just curious if anyone has a 
theory.

Cheers,
Jon
