One night before he's set to flaunt his stick skills in front of a Van Andel Arena crowd, Red Hot Chili Peppers' drummer Chad Smith reportedly surprised people in two Grand Rapids bars Saturday night.

He might have played a little bit, too.

WGRD reported Smith walked into Flanagan's Irish on Pearl Street, where he sat in with a band there, playing the drums on its cover of the Chili Peppers' "Under the Bridge." A video captured of that moment is below.

He then hopped over to neighboring Mojo's Dueling Piano Bar, where he played a little more.
