Aerosmith Considering Tour Without Steven Tyler

This is ignorant. Aerosmith is apparently considering a tour without Steven Tyler. The vocals would be done by a "guest." I'm sorry this is the dumbest idea ever. I don't know why bands think they can all just go out on the road, charge a zillion dollars for tickets and just throw anybody on stage behind the mic. Apparently Myles Kennedy, Axl Rose and Sammy Hagar are all being considered. Completely crackers.
