Action Time for Granada (not networked), 4 January 1991 to 1 March 1993 (? - may include one or more repeat runs)
Teatime quiz show played by three parent-and-child pairs, with a mixture of then-and-now rounds and theoretically age-neutral puzzle questions a la Beat the Teacher. A music round featured tunes played by the Brighton Bottle Orchestra (what's a local Granadaland show doing shipping in an act from the south coast?).
The prize endgame had the winning team going head-to-head to answer questions about their own family, secretly set by another relative - impossible to play along with but fun to watch.

The song being performed in that screenshot was "Yellow Submarine". The clues were there!
Co-creator Stuart Prebble was previously editor of Granada's current affairs heavyweight World in Action, later rising to the heights of ITV chief executive around the time of the ITV Digital debacle.
