Well, from his auto-biography book that I readed he had a lot of respect to blues musicians, and yes, black music. He plays a jam with Muddy Watters or howlin' wolf, can't remember.
Clapton sure plays a lot with the beatles in the 60's. Have even a affair with the wife of one of the dudes from the beatles. but so what,
they were friends and to me they suck together (see this show: http://www.youtube.com/watch?v=hPA8TGNjqjs&feature=relmfu), and them there's cream: clapton, jack and ginger hated each other, but they music is fucking amazing.
anyway, I have not listen do the beatles has "youtube only". I have heard the white album, and it is like a normal album. NOTHING special. now hear Vincebus Eruptum from Blue Cheer. Another level.
