Salford, Lancs, UK, 1950s:

Sam Sam, the dustbin man
Washed his face in a frying pan,
Combed his hair with a donkey's tail
And scratched his belly with his big toenail.

Rather mild, not so scatological, more 7 year old than adolescent. There wasn't much of a tune to it, a sort of vague modulation, a worn- out version of "Over the hills and far away".
