I didn't recognise this song, I think it's from his latest album - but thanks to a friendly commenter I now have the title! Paul McCartney performing on the roof of the Ed Sullivan Theater for the Letterman Show, July 15th 2009. The crowds pretty much shut down Broadway! I wouldn't recommend trying to follow the video images, just enjoy the fabulous music - but look out for Letterman walking on to the stage to the left at the very end!
