NEW YORK, July 11: Aerosmith guitarist Joe Perry collapsed on stage while performing in New York and was hospitalized, according to reports. Perry, 65, was playing in Coney Island in Brooklyn with his band the Hollywood Vampires, along with rocker Alice Cooper, when he staggered off-stage and collapsed, media reports said. A Facebook account quoted Cooper as saying from stage “If you notice one of our brothers is not onstage with us, he was very sick before the show,” Billboard magazine reported. Perry himself posted on Twitter just hours before being taken ill: “Warming up with Tommy. #HollywoodVampires @ Ford Amphitheater at Coney Island Boardwalk,” along with a link to photo of the pair playing. Hospital officials could not be reached to verify Perry’s condition. ABC News reported that hospital officials confirmed that Perry was being treated in the emergency room. (AGENCIES)
