Jimmy Fallon is known for some really great segments on his show Late Night With Jimmy Fallon, and last night was no exception!  The funnyman was joined by superstar singer Mariah Carey, along with Questlove and The Roots as well as a few awesome grade schoolers as they sung ‘All I Want For Christmas Is You‘.

Jimmy and the rest of the gang stopped by the Late Night music room, grabbed some instruments and decided to film their song.  This will definitely get you in the Christmas spirit!
