I didn't know this song until I started working with medicine circles, where I met it as the English words (not a direct translation) of a Brazilian medicine song "Pedala".
Then years later I heard it somewhere as a nursery rhyme and was surprised that that was its original function.

Maybe most adults are too thick for such wisdom to penetrate their membranes, so nursery rhymes is the path of least resistance... the child's ear-brain barrier doesn't filter out joy as much as the adult's does.
