We sang this 3-parter as Cubs in the sixties and I was still singing it as a District Venture Scout Leader in the eighties. The words were slightly different:

You can't put your muck in our dustbin....

Pepper pepper pepper pot

The last part went:

One bottle pop, two bottle pop, three bottle pop, four bottle pop,
Five bottle pop, six bottle pop, seven seven bottle pop.

And then there was the goat dance!
