Jack Black and Jason Segel Spread Holiday Cheer, Charitable Good Will

Gulliver's Travels stars Jack Black and Jason Segel are as musically gifted as they are hilarious on screen. The actors have teamed up for an animated take on Bowie and Crosby's spin on two Christmas classics, and for a good cause!

The duo will donate all proceeds from the single, "Peace On Earth / Little Drummer Boy 2010" to Blue Star Families, a non-profit for military families.
