In 1998, Kevin Dubrow sang on an acoustic version with The Neanderthal Spongecake that appeared on their album The Side Effects Of Napalm
. Cevin Soling of The Neanderthal Spongecake explained how this came together
: "Eric Clapton had done his cover of 'Layla
,' of his own song. I thought it was just atrocious, doing this mellow version and that acoustic thing. I thought it was an abomination, and so as sort of a joke I played this acoustic version of Quiet Riot's 'Metal Health.' And so, I was working out in the studio while we were working on our album, and it just started coming out really, really well - an acoustic version of the ultimate headbanging song. But it came out brilliantly, and I started adding strings and a choir, and it got pretty insane. But the problem was the original concept of the vocals was supposed to be this hard core kind of slacker vocals over this acoustic sound. But the music was just too good to sort of do that to.
So I managed to get in touch with Kevin Dubrow, the lead singer of Quiet Riot, and asked him if he was interested in singing on it. His initial response was no, because I guess Marilyn Manson was responsible for getting the band back together again, and then they were actually going to be cutting a new version of that song to sort of exploit it. But he agreed to listen to it anyway. And then after I sent it out to him, he called me immediately and said, 'I have to sing on this. Please let me sing on this.' Because it was such a radical departure, and so unexpected.
He was working as a DJ out in Vegas at the time, and so I flew out to Vegas and recorded with him, and Lindsey Buckingham's son actually was the engineer there. The whole experience was just a lot of fun, working with him. And he was great. I wasn't so much into the heavy metal music, but he was telling me how he had this terrible reputation, but I didn't know anything about his reputation or anything about him being difficult. Because he could not have been easier to work with, could not have been more professional. The whole thing was a pleasure. And I thought, hey, this could be kind of fun to do this kind of concept for a whole album. But not necessarily having people do their own materials, pairing people up with the least likely song that you could imagine them doing.
