There's no other movie...er, picture show...that's quite like Rocky Horror. The singing, the costumes, the madcap audience participation complete with props -- no wonder it's been packing 'em in since 1975. If by chance you haven't been, you've got two more opportunities this weekend at midnight on Friday and Saturday at the Tivoli Theatre (6350 Delmar Boulevard, University City; 314-727-7271 or www.landmarktheatres.com). Still need convincing? Check out photographer Steve Truesdell's photos.
