Just came across this on Youtube. Sadly no pictures - but it's one of the songs Marti had the main part to play - if you can imagine quite a few of the cast were on stage, and, from what I can remember, the dancers moving around the Chess board - this was the opening of the show - you'll hear the operatic nature of the show - and if you stick with it to the end you'll hear Marti introducing the game - in his English accent - it's the way he says the "Soviet Union" that's the most plummy.
