I am wondering if anyone else remembers the above show - a Christmas clip show, presented by Frank Muir. It isn't mentioned in his profile on this site or his IMDB page and IIRC it did not have a repeat broadcast. The titles for the show used the sloping block BBC logo to capitalise the above phrase.
It was actually a two-part show, 45 minutes each, in which Muir introduces clips from BBC sitcoms (mostly - there was also a clip from Monty Python's Flying Circus) over the years. The first show opened with Hancock (The Blood Donor) and the second show closed with Only Fools and Horses (the chandelier scene). Most of the clips are from shows we now regard as sitcom classics but with a few which are definitely less well-known now (eg My Wife Next Door).
I remember it well as my parents videotaped it, and given the expense of videotapes at the time my Dad tried several times to reuse the tape for something else but my sister and I fought against this (nevertheless we did end up having to sacrifice the first few minutes at one point). I think it was broadcast in 1983 - definitely not before as we had our first family video recorder in January 1983. For many BBC sitcoms this was my introduction to these shows, and I can still recall now the exact dialogue used for each clip. Sadly the videotape is now long gone but I'm wondering if anyone else besides myself and my sister can recall this programme.
