When I was a Guide leader I simply passed on the songs I'd leant mysel as a brownie, a guide, an ranger / young leader and then a guider round variouse camp fires, at varius camps and occasional coach rides. Guides sing, each unit has it's own particular favorate songs, which they may swap / pass on when they meet with girls from other units.... and so it goes on
A bit like moving from one folk club to another & nicking the best songs of the regulars at the 'old' folk club to sing at where ever you've moved house to ;) opps did I say nick.. obviously I meant collect ;)
