Aerosmith

I heard on the radio today that Aerosmith is considering moving on without Steven Tyler. I don't get it, how can a band like Aerosmith think any of it's members are interchangeable? No way I say! All members stay. When you've been around as long as they have they don't get to make changes like that, JOE PERRY!!!! Aerosmith is Aerosmith, it wouldn't be it with some guy from Ohio feeling in for Tyler. It doesn't work that way. Try again please.
