David Crosby and Graham Nash had a busy day yesterday: In addition to performing a brief set at the Occupy Wall Street protest in Manhattan, the folk legends made an appearance on last night's episode of Late Show with David Letterman. In this clip from the show, the duo perform "Taken At All," a number originally released on their 1976 album Whistling Down the Wire.
