The other guys in Aerosmith closed ranks and refused to appear with Steven Tyler on the final episode of America Idol. The show has secured a commitment from Lady Gaga, who will have   Clarence Clemons of Bruce Springsteen's E Street Band with her when she appears on AI Wednesday (5/25).  Clemons contributed a solo to the song Edge Of Glory to her recent album (story).  Even though Springsteen spent some time behind the scenes of the FOX show a few weeks ago giving pointers to the contestants (story), we trust The Boss shares the view Joe Perry, Joey Kramer and Tom Hamilton have about playing on the show.
