Legendary musician Paul McCartney stopped by “Late Night” this week to promote his new album, “New,” and perform “Lady Madonna,” one of his classic hits. But he also took some time to have a little fun with Jimmy Fallon in a skit.

The two bump into each other in the hallway and discovery they’ve switched accents — Fallon is delighted, because you can say anything in a British accent and it sounds cool. McCartney isn’t quite as adept at his American accent, but he gives it a good try.

McCartney’s new album drops Tuesday, Oct. 15. And speaking of accents, check out this gallery of the best accent-hiders on TV.
