The performances that we're used to seeing come out of The Tonight Show Music Room often feature the entirety of The Roots crew, plus a bunch of kiddie instruments, and more often than not Jimmy is there to help sing along - here's an example to jog your memory.

Sara Bareilles was Jimmy's musical guest back on February 27th and while we all saw her performance with The Roots that night, we didn't get to see her unplugged performance backstage until today!
