In September, Mumford and Sons’ appearance on Late Show with David Letterman was scrapped so that the band’s Prime Minister could get some extra time behind the lens. The performance finally aired on television last night, and you can watch them strum through “I Will Wait” below (via The Audio Perv). Also check out the full replay of their recent Live on Letterman webcast.
