I've only seen one episode of this show, the 11th episode to air "Maid in the Snow". That episode was very funny with all the early MTM charm I can't get enough of. The show final nail in the coffin was the program that replaced it, The Jeffersons, ran for 11 years. I hope more from the series is released but for now here's a clip from the 1974 preview show in very poor quality. [YouTube Video]
And here's the opening credits with a very underrated theme song in beautiful quality. [YouTube Video]
