Please tell me it isn’t so.  But, it appears it is.  Aerosmith will perform on the American Idol finale later this month, says Steven Tyler.  The Aerosmith front man told Rolling Stone magazine that they are playing the last show of the season.  Tyler said "When I came on board, of course they were talking about, 'Are you going to sing with the contestants?'  I said I'll do a song, sure, but it was always my intention, always, to get Aerosmith on the show. I mean, Joe's [Perry] done it. I'm ready for it. I would love to play with Aerosmith."  I am NOT a happy Aerosmith fan!
