Stephen Colbert composed the most extraordinary 'Late Show' theme music

Stephen Colbert is easing us into his new Late Showpersona with another behind-the-scenes YouTube clip.

After shaving off his TV vacation beard and hiring a new band leader, it's time to get down to business and start planning his show. Apparently, that includes composing a new theme song—a completely terrible new theme song that no one in their right minds would ever air on TV.

By the way, we're loving that "Show needs..." list on the whiteboard behind him. Items two and three are "Things to say" and "More things to say." You'll do fine, Mr. Colbert.
