i had a thread like this here about a month ago or so. it's dead now, but i got most of those songs the guys mentioned (and some that i thought of) all written down on an MSWORKS database! dont ask me why!!!!
"Woman" - Def Leppard (Sung by Floyd. The chorus will be sung by, ah, you know!!!)

"Light My Fire" - The Doors (Sung by Floyd)
"All Revved Up With No Place To Go" - Meat Loaf (Sung by Floyd and Janice)
"Bat Out Of ****" - Meat Loaf (Sung by Floyd & Janice, and because of that insane piano playing, Dr. Teeth passes out at the end of the song)
"Paradise By The Dashboard Light" - Meat Loaf (Sung by Floyd & Janice)
"Black Water" - Doobie Brothers - (an idea someone had on the old thread. It would be a collaboration with them and the Jug Band)
"Rock The Casbah" - The Clash (THE CLASH RULEZ!!! and there the only punk band that the mayhem would sound good playing)
"This Is Radio Clash" - The Clash (again)
