Bass guitar player for the Who, one of the most recognized and adored bands in the world. Also a member of Ox, a band that is relatively unknown, but quite excellent, none the less.
Famous for his "Thunder Fingers", and the fact that he never moved, or even smiled, while playing. (Some speculate that he was attempting to blend into the background, so he would not be mauled by his violent, and often blocked up, band mates).
Either way, he is considered one of the greatest bass players in rock n' roll, and has one of the most obscenely high singing voices ever possessed by a non-castrati.
