Michael Buble, Dave Matthews Hum for the Holidays on 'Fallon'

Watch the two crooners' festive rendition of 'Little Drummer Boy'

It seems like everyone has released a holiday record featuring their versions of seasonal favorites, but only Michael Bublé hums them. The signer gamely donned a red blazer last night on Late Night With Jimmy Fallon to debut his supposed new Christmas album, There's No Place Like Hum for the Holidays, with hummable renditions of "Jingle Bells," "Let It Snow," "Silent Night" and "Little Drummer Boy," a "finger-snapping duet" featuring Dave Matthews, in a turtleneck and flannel shirt.
