no one would pay that much money just for one band, unless it was sold out and they had to cough up to a tout, and even then, they'd probably be looking to go for more than one band (or maybe for no bands at all -- some people never even leave the campsite). The event sells itself out. Bleedin' Slane sold out when Bryan Adams, Macy Gray and Moby were top of the bill! People go to these things no matter what. Of course the Manics wouldn't sell it out. They'd be a much more popular headliner, though, as they have a much larger fanbase than either of those two.
