Jack Black covers Bing-Bowie Christmas hit, so does Will Ferrell - which version is best?
Jack Black and Jimmy Fallon recently parodied Bing Crosby's and David Bowie's classic Christmas duet, "Peace on Earth / Little Drummer Boy", on "Late Night With Jimmy Fallon".
Actors Will Ferrell and John C. Reilly, who played immature adults in the 2008 comedy "Step Brothers", also recorded a video of them singing the holiday hit on the website FunnyOrDie.com.
"Little Drummer Boy" is a traditional Christmas song from 1957. Bing and Bowie had used it in their 1977 duet, which was recorded for a television special.
