As you’ve probably have already read plenty of times over, probably plenty right here at The Comedy Bureau, Stephen Colbert and James Corden will be the duo that take over The Late Show and The Late Late Show, respectively, at CBS next year.

When they take the reins to CBS’ late night line-up, they will be facing off against Jimmy Fallon, Seth Meyers, and Carson Daly at NBC, Jimmy Kimmel at ABC, and Jon Stewart, Larry Wilmore, and Chris Hardwick at Comedy Central.

It’s a crowded field to be sure, but know that very few, if any, can harmonize like Colbert and Corden. Watch them sing a Christmas tune as well as Colbert giving some precautionary measures to Corden about what he’s getting into.
