Neil Young thrilled fans at a London gig on Saturday with a surprise star guest in the shape of Sir Paul McCartney.
Young was headlining the Hard Rock Calling event in the U.K. capital's Hyde Park when the former Beatle appeared onstage during the encore to join him for an impromptu duet.
McCartney hugged the Canadian star before the pair performed The Beatles' track A Day In The Life together.
The musical legends delighted fans further by playing a vibraphone onstage to close the gig.
