Peter Criss

Though KISS have cranked out their fair share of hard rocking anthems over the years, the band's 1976 ballad 'Beth' remains the highest charting song of their career. Drummer Peter Criss is often credited with the songwriting for the track, but he and Paul Stanley have different accounts as to how the track came about.

How much uglier could it get between current and former members of KISS? The iconic act will be inducted into the Rock and Roll Hall of Fame this year, choosing not to perform at the ceremony after various conflicts. However, Gene Simmons just launched perhaps the most insulting comment to date in the direction of classic members Ace Frehley and Peter Criss.
