Stephen Colbert kicked off his Christmas Carol Week last night with a special appearance by Gregg Allman and The National, who joined Colbert for a rendition of the Holiday classic “Silver Bells.” Colbert’s Christmas Carol Week will continue with guest performances by Aaron Neville, The Blind Boys of Alabama and Cyndi Lauper. You can watch a video of last night’s “Silver Bells” here. The members of The National have now shared the stage with Trey Anastasio, Bob Weir and an Allman brother.

In related news, Colbert made a nod to the jamband world a couple of weeks ago when he joked about Phish during a segment on marijuana legalization.
