Beatlemania was alive and well in Las Vegas Friday night (June 28) at Paul McCartney's second show in Sin City on his Freshen Up Tour, and another famous rocker sang back-up on one of his biggest hits.

Steven Tyler -- who's back in Vegas for his Deuces Are Wild residency with Aerosmith -- spent his night off enjoying the music of Macca. Before he hopped onstage to belt out "Helter Skelter" with McCartney, Tyler broadcast his joy to his followers through his Instagram account as he sang along with the chorus of "Hey Jude" from backstage.

He was clearly thrilled to be in the company of one of his own favorite musicians, and even brought his own trademark, scarf-draped microphone to the T-Mobile Arena for their standout moment in the deafening encore.

McCartney's Freshen Up Tour picks up again in Vancouver on July 6. Aerosmith will roll through this run of Deuces Are Wild dates through July 9 before they take their residency on an East Coast tour, which kicks off Aug. 8 in National Harbor, M.D.
