Sir Paul McCartney's surprise performance

Paul McCartney had the crowd on their feet and voices at full throttle after surprising all his New York fans who had come out to see him at Madison Square Garden. 

The American's fans were treated to two legends in New York after McCartney had called Bruce Springsteen on stage to perform and wow everyone who came in! Springsteen apparently made his way out during the encore, where they ended up performing 'I saw her standing there' not once but TWICE!

The pair last played together in 2012 where a 50-year long dream came true for Springsteen who had always wanted to perform a Beatles classic alongside McCartney.
