Jimmy Fallon is playing Santa this year and gifting us the ultimate musical Christmas present.

Stars of the animated musical Sing—including Scarlett Johansson, Reese Witherspoon, Matthew McConaughey, Seth MacFarlane, and Tori Kelly—teamed up with the comedian and The Roots for one spectacular a cappella rendition of Paul McCartney's 1979 classic "Wonderful Christmastime" for Tuesday's episode of The Tonight Show.

In the segment, the celebrities appear across a series of nine colorful panels as we hear the first lines of the festive hit. When the chorus hits, the screen switches to a snowy night and we see the carolers decked out for the holidays in earmuffs, scarves, and even a Santa hat, as sleigh bells ring in the background.

Then, one by one, the actors and actresses are replaced by their animated characters from Sing as they continue performing the holiday tune.

Just when we think things can't get any better, the group is joined by none other than the iconic Beatles musician and author of the song himself. McCartney proceeds to take Christmas to another level!
