Perry Farrell: Sometimes the best thing to do, when changing course, is to go all the way. It's hard to imagine a character more unlike Cowell than Farrell, L.A.'s own utopian hippie-punk trance dance ringmaster. But remember, Farrell founded Lollapalooza. Hes got that P.T. Barnum side. If nothing else, "Idol" would be freakier with him on board.
