Watch Jimmy Fallon, Paul McCartney and “Sing” Cast Perform A Cappella of This Christmas Song

Jimmy Fallon gathered Paul McCartney, The Roots and the Sing cast to perform “Wonderful Christmastime” a capella on The Tonight Show. Matthew McConaughey, Reese Witherspoon, Scarlett Johansson, Seth MacFarlane and Tori Kelly warm up their vocals and perform in the Brady Bunch-like grid with red and green backgrounds.

While McCartney’s version of the classic Christmas tune will forever be a favorite, these stars (with the help of their film characters) make it an incredibly cheery alternative. Wearing scarves, hats and other winter wear, the A-list actors-singers will have you counting down the remaining days until Christmas with even more fervor.
