Yeah, it's funny, but there are a few things that aren't absurd enough. If there had been a Coachella '90, Jesus Jones would have been there. (In fact, I saw them at a festival that year...they were the pre-headliner one night and they hadn't even hit in the US yet.) I think Midnight Oil could pull a crowd even today. Seal, too.
And The Three Tenors "in the tent" would be bad-ass.
For some reason, the funniest one to me is Roxette. I don't even remember their song, but I can picture the cover. I used to manage a chain record store, and we had a crapload of them used that we could never get rid of.
