An informal survey

[BklynBlue]

thanks for the additional info - something else I'll need to keep an eye out for!
Very interesting - this is exactly the type of information that I wish you could find in the available discographies / sessionographies - not only who is singing lead, who is playing which instruments (I say that because Jeremy shows himself to be much more of a "team player", mainly on the BBC sessions, taking over on piano while Peter Green plays lead guitar, even when he, Jeremy, is on lead vocal - and he's rarely, if ever, given credit for it), but also, if the song is a cover or an original -

Another good example is their take on "Mean Old World", recorded for the Aug '68 BBC air-shot - theirs is based on T-Bone Walker' s late '50's recording of the song that he did for Atlantic Records.
He changed the lyrics and the intro from his original Black & White version and most British groups, most famously, Derek & the Dominos (there's the E.C. connection again!) used Little Walter's recording (different last verse) for their template
