NME reports on the "lunchtime gig" that Paul played earlier today in London.
The show was the smallest the former Beatle had played since he performed at the Cavern Club in his native Liverpool in 1999. The London venue has a capacity of 300 – with The Rolling Stones' Ronnie Wood among the audience members for the show.
Billed on tickets as A Packed Lunch At The 100 Club, McCartney played a 28-song set, kicking off just after 1pm (GMT). He greeted the crowd with a casual "Alright?", joking that his slightly late arrival was due to the traffic.
After he said that he thought the 100 Club, which is under threat of closure, needed to be saved, a shout of, "Why don't you buy it?" came from the crowd. "You buy it, I'll rent it!" the Liverpool legend quipped back.
With a plea for "No heckling, now!", he and his band launched into 'Matchbox', a Carl Perkins song that the Fab Four used to cover back in 1961.
