The Motor-City Madman drops in on Dave for a little Xmas cheer as they parody Bowie and Bing’s classic duet
The two mimic the lines exchanged by Bowie and Bing in the classic clip from the Seventies before the Nuge suggests they “take a whack” at one of the song’s from Letterman’s holiday songbook.
Needless to say, it’s pretty funny and Letterman just might be a surprisingly good singer . . . or not.
