Ronnie James Dio fronted Richie Blackmore's "Rainbow" (song "Man on the Silver Mountain"), he fronted a revamped Black Sabbath before Ozzy went back, then struck out on his own. He's good.
Motley Crue was OK, I guess (they covered "Smokin' in the Boys Room" pretty well).
Don't talk to me about Poison (
*shudders*).
