Hmm.. Giving this one a little thought.
Cannibal corpse could open with some soft ballads such as Force-fed broken glass or Skull Full of Maggots.
Then for the ravey-daveys out there, perhaps some dance music/ drum and bass or whatever they call it for ten minutes,
and back to the good stuff
Something for the classic rockers with some Metallica or Maiden.
Something for the younglings?
Kelly Osbourne or Avril Lavinge?
Metallica have a go for a bit.
then the headliner:
Ozzy Osbourne,
That covers a fair bit.

I'd go just to see Corpse again.
This isn't real, is it? lol
