And not just any friends – the 76-year-old was reunited with Sir Ringo Starr, 78, on drums and joined forces with Rolling Stone guitarist Ronnie Wood, 71. The supergroup lined up to perform The Beatles’ 1969 hit Get Back at London’s O2 Arena and close the UK leg of Freshen Up tour. Sir Paul stunned the sell-out crowd before the encore of his show on Sunday night, saying: “We’ve got a little surprise for you. It’s a surprise for us, actually – it only happened today.”
After the performance, Sir Ringo said: “I don’t know about you, but that was a thrill for me.
“I’m just going to let that moment sink in,” McCartney added as the two musicians left the stage.
His fashion designer daughter Stella McCartney, 47, posted an Instagram snap of herself with the legends, along with actress Dame Emma Thompson.
Former One Direction star and actor Harry Styles, 24, US actor Rami Malek, 37, who took on the role of Queen frontman Freddie Mercury in the biopic Bohemian Rhapsody, and The Who’s Roger Daltrey, 74, were among stars in the audience.
Fans of the Fab Four heard plenty of their hits during the three-hour set. Some felt that Christmas had come early, with Matt Hutson tweeting: “Half The Beatles and a Rolling Stone. Merry Christmas.”
Another added: “Yes that is Paul McCartney and Ringo Starr! I was there and cried!” Sir Ringo was delighted to be back on stage with Sir Paul.
On his Twitter account, a picture ture of the moment was posted along with the caption: “Having a great time at the O2 with Paul, Ronnie and Ringo.
“A great night love you peace and love.”
Meanwhile, Ronnie revealed he had followed the fans by heading home on public transport. The guitarist concealed his identity by hiding under a hood. On a Twitter video he said: “I’m going to the Tube. It was great to play with Paul and Ringo.”
Sir Paul will return to the stage in March when he will perform a series of dates in South America.
The Freshen Up tour then moves on to the US for its final gigs in the summer.
