Billy Joel did it again. The "Piano Man" is famous for inviting surprise guests on-stage, and on Friday night Joel welcomed Jason Bonham on-stage during a show at Philadelphia’s Citizens Bank Park. The son of Led Zeppelin’s John Bonham sat at the drum kit, as Billy Joel’s guitarist Mike DelGuidice took over on lead vocals, and Joel and his band cranked out Zeppelin classics, “Whole Lotta Love” featuring a drum solo by Bonham, followed by “Good Times Bad Times” with Billy taking the mic back.
