When one thinks of Christmas songs, Iggy Pop and William Shatner probably don't come to mind, least of all together. But the two have, indeed, teamed up for a version of classic Christmas song.

Iggy Pop appears on a soft, nearly spoken-word rendition of "Silent Night." While nearly all of the album's tracks are covers of beloved carols, it does include one new, original song, "One for You, One for Me."

The collaboration is part of Shatner's first-ever holiday album, Shatner Claus, and it's not the only one on the album. Other notable guests include Black Flag frontman Henry Rollins, Billy Gibbons of ZZ TopBrad PaisleyTodd RundgrenJethro Tull singer Ian Anderson, YES keyboardist Rick Wakeman, King Crimson saxophonist Mel Collins, Lynyrd Skynyrd drummer Artimus Pyle, the Cars guitarist Elliot Easton and more.

While Shatner Claus might be getting the most buzz due to its star-studded tracklist, it's actually Shatner's second release this year, preceded by country album Why Not Me?

Shatner Claus is out now on CD and limited-edition red vinyl.
