Jimi, Jeff, Pete, Jimmy, Eric; I could go on, but the point is we all remember the guitar heros who in the 60's revolutionized the way the instrument could be played - and there were many. But on bass, there was really only one. (Great writer and singer, too.) John's work will always have a place in my collection.
Here's the liner blurb on John from their first LP, 1965's US Decca release of "The Who Sings My Generation":
"Bass guitarist John Entwhistle, 19, is the quiet, moody one who seldom moves, but, as he says, if someone didn't act as an anchor the whole group would just take off and fly"
Here is the one from their second, 1966's "Happy Jack":
"It is not often that an accomplished French horn, cornet and tuba player turns up in a pop group on bass guitar. John is the exception. He is content to stand quite still and look disinterested, but his music proves he is not."
