Looks like several songs, and variants therof, have been put together in various permutations. Whoops! Quite a sentence. Verses by Odum, Oliver and Spaeth cited by Stewie seem to show what can happen, in the 150 or more years after the "original" songs, which we can never collect in their earliest form.
The verses with "'Most done ling'rin' here" from the earlier thread catches in my memory, I believe that I have heard it, but I may be deluding myself. Rich r, was there any more of it in that book? Or maybe someone can find a bit more somewhere...
