Jimmy Fallon, Mariah Carey & The Roots Sing “All I Want For Christmas Is You” (w/ Classroom Instruments)

I have to concur with Jimmy Fallon that Mariah Carey's "All I Want For Chritsmas" is one of my, if not thee favorite Christmas song of all time (only topped by Donny Hathaway's "This Christmas"). Although the "Late Night version" will never outshine the original, the school instrument twist of the Maraih Carey classic is still a lot of fun.
