Mark,

I have to disagree about Dylan. Sure, he doesn't do Bluegass exclusively, but when he does he sure sticks with the tradition. Listen to his covers of Ralph Stanley's "I Am The Man, Thomas" and "Somebody Touched Me". He opened his recent Toronto show with a Bill Monroe song. His current band has some wonderful players who sure would fit in at any Bluegrass festival.

Pat Boone was not an R&B artist because he eliminated the soul of the music whereas Bob is careful to preserve it.
