Segel and Black Rock Out Crosby and Bowie Style

Hands down, one of the strangest collaborations in music history has always been Bing Crosby and David Bowie combining their vocal talents for the seasonal favorite, "Little Drummer Boy/Peace on Earth." As strange as it sounded on paper, it turned out to be a holiday classic. Thirty-plus years later, actors/musicians Jason Segel and Jack Black have provided a bit of rock to the number and keep the song just as enjoyable.
