One of my favorite shows, ever, was the time I saw Quiet Riot (2002 or 2003) at a tiny bar in Concord, California with 200 or so other people. It was a blast. They wore spandex. And did all their hits.
There's no cause of death (apparently the guy was sober and straight).
Anyway, I don't have any Quiet Riot music, but I did find 3 versions of Cum On Feel The Noise by THE CRACK, ONE WAY SYSTEM and The Humppa King ELIKALAISET
