Paul McCartney, cast of Sing do a cappella “Wonderful Christmastime” with Fallon and The Roots — watch

Matthew McConaughey, Reese Witherspoon, Scarlett Johansson, and Seth MacFarlane sing along

‘Tis the season for caroling, and with his well-documented love of a good sing-along, you know Jimmy Fallon’s getting in on that action. On last night’s episode of The Tonight Show, the host and his house band, The Roots, were joined by the cast of Illumination’s animated comedy Sing (Matthew McConaughey, Reese Witherspoon, Scarlett Johansson, Seth MacFarlane, and Tori Kelly) for an a cappella version of “Wonderful Christmastime”.

The live-action actors and their animated counterparts weren’t the only surprise singers, though. Sir Paul McCartney himself showed up with a bit of the holiday spirit, joining in for the last verse and chorus. Watch video of the jolly little rendition above.
