Steven Tyler was knocked from the stage by Aerosmith bandmate Joe Perry Tuesday night after they got into a shoving match onstage while performing "Love in an Elevator" in Toronto. First, Tyler bumped Perry on the hip, then Perry knocked Tyler into the crowd. Tyler then jumped back on said, "It ain’t gonna happen again!"

This isn’t Tyler’s first pratfall: he broke his shoulder after falling from the stage last year. In March, he quit the band temporarily after another fight with Perry.
