Did you hear the one about Emma Stone, Paul McCartney and Billie Jean King walking into a bar? Well, that's what really happened on Friday night when the trio showed up at New York's Club Cumming--owned by actor and Broadway star Alan Cumming--to perform show tunes onstage.
"Proving the 'anything can happen' mantra, last night at @clubcumming I sang 'Part of Your World' [from Disney's The Little Mermaid] with Emma Stone and Paul McCartney backed us on harmonica," Cumming wrote on Instagram alongside a pic of the three of them.
"Also reveling were Billie Jean King and her wife Ilana!" Adds an Us Weekly source, "People were really chill about it and didn't whip out their phones...[They] asked people not to record it, which everyone obliged."
