"Chappelle surprised audience members in New York City, when he followed the final act on the bill at the Comedy Cellar around midnight and riffed for about 45 minutes onstage. At the end of his set, Rock joined him onstage, and undoubtedly fulfilled the long-held dreams of many in the room.

Dave’s like, let’s just do it Wednesday. Unannounced!” Rock said. But the elder of the two comedians said he’s filming a new movie this spring and would need to get his new material ready before he would commit to a tour. (He did say he could be ready by Halloween.) This is probably what’s best for us fans—Chappelle and Rock have appeared together at the Comedy Cellar before, but it would be great to see a full-on tour or concert as opposed to more occasional impromptu duets."
