Jimmy Fallon is, of course, a comedian, but he is also a pretty decent musician. He’s been adding lots of music to his Late Night show in very unique ways, like when he performed Your Body with guest star Christina Aguilera with The Roots using office equipment as instruments. 

Last summer he launched his very own house barbershop quartet The Ragtime Gals. Jimmy recently performed SexyBack with his quartet, but made it a ‘quin’ with special guest Justin Timberlake. Naturally, the video is going viral.
