It's a Knockout 1966 

I loved this as a kid. Stuart "ha ha ha" Hall and Eddie "up and under" Wearing commentated and refereed a 70's (they did it first) Gladiators. With Jokers doubling the points and the marathon to build up points on, it all lent itself to a hilarious competition. It really hotted up when meeting European teams, in what was known throughout Europe as Jeux Sans Frontiers.Peter Gabriel first brought this to my attention.
