The Starland Vocal Band Show (1977)

Summer replacement comedy/variety show, hosted by the eponymous Washington D.C.-based folk-rock group (Bill and Taffy Danoff, Jon Carroll, and Margot Chapman), one-hit wonders ("Afternoon Delight," a number-one hit the previous year) who'd started out as John Denver's backup group. The comedy was provided primarily by veteran D.C.-based satirist Mark Russell and David Letterman, who got his first national exposure with this program.
