Ah, I'm glad I'm not the only old git that remembers this! I actually looked into it some time ago and dug up this site ( http://www.chez.com/jeuxsansfrontieres/1978.htm
) which has some information about it (scroll right down and there are a few pictures too) - it might just jog a few memories.
I remember being really pleased as a kid because I was a big Tintin fan - we didn't have t'internet when I were a lad - so I lapped it up! In fact back in the old days "International It's a Knockout" was one of the highlights of the week... (sad eh?)
My memories of the show are also a bit vague (my only clear
memory is of the plastic Tintin wigs, disturbing...) so I thought it might be helpful to summarise some of the info from the site:
It was held in Rochefort, Belgium in 1978 and the game titles translate as: Help !, The Horrible Spider, Al Capone's Gang, Danger Anaconda, Fragile, The Atomique Pile, Here Snowy !, Chang and the Yeti
and The Castafiore Rescue
. The games were sourced from "The Shooting Star", "America", "Picaros", "The Broken Ear", Destination Moon", "Prisoners of the Sun" and "Tibet".
The team from Germany ended up winning it with the Belgian team coming in joint second with Italy. The UK team from Crewe/Nantwich could only muster a feeble 5th place (out of 7). The French team came last... :)
