The cast of Rock of Ages turned it up to 11 on July 21, when Def Leppard drummer Rick Allen stopped by Broadway to check out the ‘80s metal musical! Allen, known as Thunder God to his fans, famously overcame the loss of his left arm in an auto accident in his early 20s to continue drumming with the band. After checking out the show that Def Leppard helped inspire (“Rock of Ages” is a track off the band’s album Pyromania) Allen headed backstage to party like rock stars with the show’s talented cast.
