Paul McCartney, The Roots, and the Cast of Sing Did an A Cappella Christmas Carol

On a recent episode of The Tonight Show, host Jimmy Fallon was joined by The Roots, the cast of the upcoming animated film Sing, and, incredibly, the one and only Paul McCartney to give a spirited a capella rendition of "Wonderful Christmastime."

Just to clarify: including the Sing cast in this number means appearances by the likes of Reese Witherspoon, Scarlett Johansson, Matthew McConaughey, and Seth MacFarlane.

The medley features each singer in a different moving tile, quite the accomplishment to put this entire thing together! We'd like to take a minute to thank the editing team behind this glorious vid, whomever you are.

Take a look below--if this doesn't put you in the Christmas spirit...well, other things still might. But this is pretty cool.
