A friend of mine is trying to work out the words to the last verse of Grandpa Jones' version of "Old Dan Tucker." Can anyone help?

Any thoughts or sources would be much appreciated. I've checked the DT and also Google as many ways as I can think of, to no avail. And my friend has put the CD track through every computer slow-downer that she can lay her hands on.

Thanks,
