Sir Paul McCartney and Sir Ringo Starr reunited on stage at London’s O2 Arena, performing classic hits like ‘Helter Skelter’ and ‘Sgt. Pepper’s Lonely Hearts Club Band.’ The concert marked the finale of McCartney’s Got Back tour. Rolling Stones guitarist Ronnie Wood also joined for a special performance of ‘Get Back,’ featuring McCartney’s Hofner bass guitar, recently recovered after decades of being stolen.
