Late-night television's countdown to Christmas continues. Jimmy Fallon unveiled his most recent a cappella efforts on Tuesday's "Tonight Show," tapping the cast of the new animated film "Sing" to cover Paul McCartney's "Wonderful Christmastime." The special guests? The Roots and Macca himself.
Reese Witherspoon, Scarlett Johansson, Matthew McConaughey, Tori Kelly and Seth MacFarlane voice various animals with vocal chops on "Sing." Arranged as usual in a configuration reminiscent of "The Brady Bunch," their animated characters also pop up in the segment while they make merry.
The fun rendition of the holiday tune is, of course, kicked up a notch when McCartney joins the party.
