Hugh Hefner's weekly soiree was on a set made to look like a penthouse, where he (along with Playboy Bunnies usually in tow) partied with guests, including Marvin Gaye, Mel Torme and the Smothers Brothers. `After Dark' did well in urban areas, but had difficulty getting on the air in much of the country, and lasted just one season. Ten years earlier in Chicago, Hef hosted a similar show titled `Playboy's Penthouse.' Comedian Lenny Bruce was his first guest.
