John Alec Entwistle (b. October 9, 1944, d. June 27, 2002) is probably the most influential bassist in rock music. Before Entwistle came along as a member of the Who, bassists seldom stood out for their playing and few casual listeners knew or cared what purpose the four-stringed instrument served -- after he came along, everyone knew. Born in Chiswick, Entwistle was a member of the Confederates with Pete Townshend while still in grammar school in 1959. Trained in both the piano and the French horn, he was one of the most musically accomplished teenagers ever to play in a skiffle band. Invited by Roger Daltrey to join his band, the Detours, Entwistle accepted, and was joined soon after by Townshend. With the addition of drummer Keith Moon, this band, later renamed the High Numbers and finally the Who, became part of the second wave of successful British Invasion acts, getting their recording act together in 1964 and 1965.
