Ace falls.... horrible playing.
Yeah, there have been a number of bands that have done some great KISS covers.
Darrell said it himself, if not for Ace Frehley, there never would have been a Dimebag
Cold Gin was written by Ace (but sung by Gene since Ace didn't have the confidence to sing it himself.)
He also had a sticker of Kiss on his guitar and I think a tattoo of Ace on his chest.
