Paul McCartney’s Wild Night In Brooklyn

Paul McCartney had a bit of late-night fun on Friday (September 22) after his show at the Barclays Center in Brooklyn. 

McCartney not only showed up at British actor Alan Cumming's Club Cumming in Manhattan for some post-show revelry but -- sporting an "I Saw Paul McCartney In Brooklyn" jersey -- hopped on stage with Cumming and actress Emma Stone to play harmonica on a rendition of "Part Of Your World" from The Little Mermaid and subsequently hit the dance floor for the rest of the night. Cumming and Stone were celebrating the release of their new film Battle of the Sexes about Billie Jean King, who was in attendance, and Bobby Riggs.

Footage of the impromptu performance has surfaced throughout the social media world.
