Chad Smith at Flanagan's in Downtown Grand Rapids, Michigan from on Vimeo.

The Red Hot Chili Peppers will be playing Grand Rapids' Van Andel Arena on Sunday, June 25, but it seems they may be in town a day early.

Folks enjoying a drink and some live music at Flanagan's Irish Pub in downtown Grand Rapids were shocked to see the Peppers' drummer, Chad Smith, walk into the pub Saturday night, but then things got even better.

Smith decided to hop on the drums with the band that was playing, and join them for a cover of the Red Hot Chili Peppers' hit song, "Under the Bridge". How freakin' cool is that?!? Luckily for us, my buddy Andy was able to catch video of the performance.

Posts on Facebook and Instagram also indicate that Smith walked next door and hopped on the drums at Mojo's Dueling Piano Bar.
