Jimmy Fallon, Mariah Carey And The Roots

The folks over at Late Night with Jimmy Fallon have done it again. Using musical instruments you could probably find in an elementary school classroom (the schools that still have music class, that is) Jimmy and The Roots have teamed up with Mariah Carey to create a little piece of holiday cheer.   However, the most delightful part might be the chorus of children who pop up in the foreground.
