Barrygeo, I think B.B. King is great; in my early days, one of the records that had a strong influence on my own lead guitar playing was Live At The Regal. But again, we're talking versatility here -- and in my view, B.B. has to be in the running for LEAST versatile guitarist. The man can do a whole lot with one note, but in the end it's still only one note, and he just plays it over and over again.
