Danny Gallagher, one of my fellow scribes over at TV Squad did a post about this late 70s game show pilot hosted by David Letterman. It's a rather bizarre, lame game show (the panelists ask the questions? Letterman has to walk next to the contestants in the last round?), but look at those celebs! Robert Urich! Michael McKean! Jo-Ann Worley!
It doesn't look like Letterman is thrilled with the show but he's an entertaining, different style of game show host.
