The retrospective special looked back at the history of My Three Sons and The Partridge Family (other than featuring single parents with a large family, the two series had no narrative, or even a studio link). The special was notable for featuring footage from early black and white episodes of My Three Sons that, at this point in time, were not in syndication . While most of the collected casts gathered in a studio to reminisce, Demarest appeared in a brief pre-taped segment . </P>
