Joe Perry Bumps Steven T off stage

Joe Perry allegedly knocked Steven Tyler off stage during an Aerosmith concert in Toronto.

In footage on the net, Tyler can be seen bumping Perry, causing him to lose his balance slightly.

Perry then knocks the band's frontman with his hip, leading Tyler to fall off the stage and into the audience.

Both Perry and security guards helped Tyler to his feet. The singer then said: "That won’t be happening again."
