He was not a bass player, he was a bass guitar player. Here, The Ox shows you the difference.

June 27th of 2002, JOHN ENTWISTLE, the amazing bass guitarist for THE WHO, was found dead in his room at the Hard Rock Hotel and Casino inLas Vegas.  He was 57.  Cause of death:  A heart attack . . . brought on by excessive use of cocaine AND a whore. That’s how a rock star goes out I guess.

Thanks for the great music John.
