Joe Perry is best known as the guitarist of rock band Aerosmith, but he has a sideline with Hollywood Vampires, the band he is a member of alongside Johnny Depp and Alice Cooper.
They were playing a gig in New York last night when Perry, 65, was seen sitting on the drum riser and then walked off stage, where he reportedly collapsed.
A fan caught the incident on their cameraphone, which you can see below:
Rolling Stone report that he was taken to hospital, where he is 'stable and resting', while his bandmate Alice Cooper reportedly said that he had been 'very sick' before the show and was now 'with family and under the best care'.
