Mumford & Sons Play Rousing 'I Will Wait' on 'Letterman'

English foursome brings a horn section to 'The Late Show'

Mumford & Sons revisited the scene of their U.S. television debut last night, returning to the Late Show With David Letterman for a rousing performance of "I Will Wait," from their new album Babel. A horn section fleshed out the chorus over a sturdy bed of guitar and banjo and, of course, the close vocal harmonies that have become a band trademark.
