Billy Joel was joined by some special guests on stage during his performance at Chicago’s Wrigley Field Thursday night.

Actress and comedian Amy Schumer (Trainwreck, Inside Amy Schumer) and Jennifer Lawrence (The Hunger Games, Silver Linings Playbook) – along with an entourage – joined the Piano Man for a little backup singing and dancing during his performance of the 1983 hit “Uptown Girl”.

But providing back-up wasn’t enough for Schumer and Lawrence, who quickly decided their bit would be better from atop the piano.

The guest appearance wasn’t entirely random; in the movie Trainwreck, Amy Schumer’s character does a dance sequence to the song along with the New  York Knicks cheerleaders.

Billy Joel will perform in San Francisco, Denver, Houston and Charlotte through the end of the year, in addition to his monthly residency at New York’s Madison Square Garden.

Earlier this month, the 66-year-old welcomed a baby daughter with his wife Alexis.
