The OP has been hanging around for many years, Leenia. He'll always come back ... sooner or later :-D
Jim, I think you've hit it for the Chorus line ...
"Settle up some old dues, make a few things right"
...and for the Verse 4 line ...
"Then we'll sing this song to the tune that the rooster crows."
... At least, that's what I'm gonna sing until I can ask them :-)
I'm not so sure about the Verse 2 line though. I'm thinking that ...
"And the nights are long 'til the sun comes over the hill"
... sounds closer to what they are singing. But I'm still not convinced that the italicized part matches what they're singing. Sooner or later I'll get to hear them sing it or hear another recording and we'll see then. [Actually, I was mildly hoping that someone here might actually KNOW them and be able to ask :-) ]
Meanwhile, now I've got reasonably accurate words to sing.
