This is just awesome. Mariah Carey joined the world's greatest house band, The Roots, and Jimmy Fallon to perform her classic Christmas Carol.
"All I Want For Christmas" is one of those records that people of all ages know and is one of the best holiday songs ever written. Joined by Jimmy Fallon on the woodblock and Black Thought and Questlove backing them up, the crew gives you a nice feel good viral.
A little fun fact is that this Christmas marks the song turning eighteen years old. Congratulations, we are all officially old. Check out the performance of the song after the jump.
