Should add that for some reason (probably to help with meter), most versions I know start with "Here's good luck to the quart pot", with the callback starting at
"Oh, the quart pot, pint pot, half a pint, gill, quarter gill, nipperkin and the brown bowl,
Here's good luck, (etc.)

Similar songs include "Rattlin' Bog", "Hole in the Bucket", and 20 billion other songs children have used to annoy their elders over the past couple centuries...
