I still say Stewart Copeland for best drummer, but I also like Cozy Powell, Roger Taylor, Mickey Curry (except on the 18 til I die album), and of course Ringo. Oh, and Rick Allen - extra kudos for doing it with one arm!
Bass players, well, Paul, naturally, and also Sting, John Deacon. Not that well up on bass, so that's about it.
Guitarists, well, I appreciate Hendrix's talent, but he's never been my cup of tea. Bit too psychedelic for me. My fave guitarists:
George, of course!
And I can't think of any others that really grab me. I suppose it'll do, though!
