If I remember rightly it was pre-empted by a gang of kids walking around the playground chanting 'Who wants to play, British Bulldog'.
Could possibly be an early 60's forerunner which evolved into British Bulldog 123 though.
That reminds me of the chant "all in for football, no girls playing," which would be recited as the boys marched around the playground, arms around each others shoulders, until we had a sufficient number for a match.
