As he took to the Pyramid Stage on Saturday night, the former Beatle became the festival’s oldest solo headliner, a week after he celebrated his 80th birthday.
To mark the momentous occasion, Sir Paul treated the masses in the crowd to a selection of his own songs as well as beloved tracks by The Beatles and from his later group Wings.
During his more than two hour set, he played a range of classic song including Hey Jude, Blackbird, Live And Let Die, Ob-La-Di, Ob-La-Da and Get Back.

It’s here! Greeting the crowd at the start of the show, Paul said: ‘Oh man, it’s so good to be here. We were supposed to be doing this three years ago!’
The electrifying show was further amplified as he introduced Grohl to the stage to sing I Saw Her Standing There and Band On The Run.
The Foo Fighters frontman revealed he had flown in from the US especially for the appearance, but admitted that the journey was not without a few bumps as he had multiple flights cancelled but noted he would “never miss being on stage” alongside Sir Paul.
Following Grohl, Sir Paul announced he had another surprise all the way from the east coast of America as Springsteen took to the stage.
After the US rocker wished Sir Paul a happy 80th birthday, they played Glory Days and I Wanna Be Your Man.
Sir Paul also remembered his nearest and dearest during the headline set including dedicating a piano-led version of My Valentine to his wife Nancy and Something to his Beatles’ bandmate George Harrison.
Dapper: The performer donned a smary navy blue Nehru jacket for the opening moments of his headline set, but later removed it, telling the crowd it would be his ‘only wardrobe change of the night’
