This group of performers was introduced by David Letterman himself. Everyone enjoyed the latter's appearance.

In this guest appearance, each participant performed a different song. Bob Dylan sang “Maggie’s Farm,” while Mumford & Sons did “The Cave.” On the other hand, The Avett Brothers sang “Head Full Of Doubt, Road Full Of Promises.” Failed to watch this performance?
