In 2012 at a Bruce Springsteen show, Paul McCartney joined him on stage and the audience got a night to remember.
It was the second night of Hard Rock Calling and unfortunately their set was cut shot when organisers turned off their microphones after they broke the venue's sound curfew.
Springsteen played a 29-song set, which lasted three and a quarter hours in total.
Bruce Springsteen said he was amazed when concert bosses pulled the plug on his performance with Paul McCartney: "I wasn't aware the plug had been pulled, and people couldn't hear what I was singing. Afterwards I said to Paul, 'I can understand them pulling the plug on me, but you? Aren't you a knight?'"
