Listen to Arcade Fire on iHeartRadio

Indie rockers Arcade Fire are bringing some holiday cheer to the latest episode of Zach Galifianakis' web series "Between Two Ferns." 

The group's choral version of "Little Drummer Boy" closed out the "Happy Holidays Edition" of the mock talk show. 

Various members of Arcade Fire took lead vocals on the Christmas carol, while frontman Win Butler appeared a little disinterested and even lit up a cigarette mid-performance.
