Blind Item #6 - Reader Blind

This permanent A list musician is considered one of the greatest of all time.  He is still active but largely out of the public eye.  He was part of two big bands.  His most famous musical moment was with the more successful of the two bands and was in a song based on a  real event.

He has always had the reputation as a genuinely mean and unpleasant person to deal with and could be unpredictable and violent. Groupies especially hated him as one of his favorite things to do after the sex was over was to squat over a sleeping groupie and defecate on her head and chest.
