I'm not sure what we English can bring to the blues other than an academic appreciation. Cuckoo, nest, that sort of thing.

Was it Sonny Boy Williamson who said "Those white boys want to play the blues real bad, and that's how they play them, bad"?

I think it was about one of the slightly later-than-first-on-the-scene London blues gods bands, like the Yardbirds, or the Blues Band, not I think Mayall.
