At least Steven Tyler is in good company ...
Meat's broken his leg twice falling off stages and apparently fell off the stage in 1994 as well, but didn't break anything. Jim Morrison regularly fell off stages. Michael Jackson fell off and broke his (own) nose. Stevie Wonder fell last year during a Barack Obama election rally. Other tumblers that I can think of include Stevie Ray Vaughn, Hank Williams, and Noel Redding (Hendrix's bass player). And, Bono regularly gets very close to The Edge.
