We showed you the video of three random folks jamming together on a sidewalk in front of a grocery store. The video went viral and Jimmy Kimmel invited them to perform on his show. Then they took "jam session" to a whole other level!

The guys come on one at a time, in the same clothes they were wearing in the original video. I thought Kimmel was screwing it up at first when he joined/squeaked in on Clarinet, but then the rest of the band joined in, along with some other guests, including a choir... the result was epic...
