Steven Tyler is expected to join his bandmate Joe Perry onstage when the musician's Joe Perry Project opens for the Who's farewell show at the Hollywood Bowl on Wednesday night (September 24). It has been reported that Tyler would join Perry for three songs as a special guest at the venue, according to the Hollywood Reporter. Last week, the pair also reunited for a live performance at the VMAs in tribute to the late Ozzy Osbourne, performing the music legend's 'Mama I'm Coming Home'. The pair were joined on stage by Yungblud. More on this here.
