Clapton's take on the blues has affected and pleased far nore people than the artists you mention. That's what clapton did with his life, and with the form of music called the blues.

Tears in heaven, and the unplugged album came out a few years after my Mum died. I can remember my father hearing the song and his eyes filling with tears as he was remembering his wife.

Just how many folks does a song have to make people feel the humanity within themselves - before its a folk song.

Sorry we're back to 1954 and all that.....
