A mate and I went to see him and the Copper Bottom Band in Oxford, earlier this year, he and the band were ACE, one of the best gigs I have been too.
I've seen him live. If you can't sing The Blues authentically, in your own voice, then don't sing at all.I watched a documentary about him and his band, he is very honest that his fame and fortune has given him the chance to do something that others who are far more talented than him could never do.
But he has a deep rooted love of the Blue going back to before he was famous, (he insisted that the intro music to A bit of Fry and Laurie was Mardie Gras in New Orleans, by Prof Longhair, his favourite Blues singer).
He's an accomplished pianist, I agree that his singing style is a bit odd for a white guy, but you can't sing the blues sounding like some posh kid from the Footlights.
Here is is proving it, keeping up with some awsomeness too; Scruggs, Gill, Stuart, Lee, etc. all first class players...
jeez, very nearly like Jazz with guitars with the important distinction that they were all playing the same tune, phew.
Bluegrass. Mountain Music. The original white persons' blues.And there is actually a tune. Saw a poster the other day for a Music and Jazz festival, proof as if proof were needed.
