I LOVED this programme but I only liked it when Fred Dineage or Bunty(?) were answering the questions and puzzles because they were always funny. The other two blokes on the panel (who I think were both called Jack) always gave boring explanations about things I wasn't interested in like barges and electrical circuits..lol.
In fact one of them went on to present THE most tedious programme about country pursuits and horse brasses etc. in fact I'm sure he must have been the inspiration for The Fast Show's Bob Fleming.
