This looks like it was from 1990 as the intro ident BBC Two was not used from 1991 as BBC One and BBC Two got a new look, so 1990 if this is one of Rory's BBC era shows.
5:12 - a truly great piss take of Never the Twain, which was a sitcom which seemed to never know when to end. It ran from 1981 to 1991 and only really forced to end when Thames Television knew they lost their franchise.
