On page 139 of Joe Perry's book, ‘ROCKS: MY LIFE IN AND OUT OF AEROSMITH’, Joe talks about how Aerosmith was only ever blown off the stage once, upstaged by, you guessed it, Rory Gallagher. @Joe Perry,@IamStevenT,
""We played the outdoor Schaefer Music Festival in Central Park (New York City) - fifty thousand people strong - where Rory Gallagher opened for us. He was a hard-drinking Irishman with his own brand of blues rock that captivated the crowd. In between songs, he'd belt down another Irish lightning that seemed to add to his energy. He kept playing and playing, way beyond his cutoff time. Afraid of inciting a riot, the promoters let him go on - at our expense. When he finally left the stage, the crowd, wanting more Rory, started throwing cans and bottles. We set up among the flying debris. The debris kept flying during our set. Brad got hit and a broken bottle cut Joey's arm, but in defiance, we held our ground and played, only to be cut off by the curfew. I remember it as the only time that we were blown off fair and square in true rock-and-roll style. That night Rory Gallagher was just too good to stop". -- Joe Perry
