Years ago I heard Gordon Bok sing a rowing song he'd written, and while it didn't have Nancy in it, it had 'lady' and 'Nancy' could easily be substituted. I don't know if he ever recorded it, but what I can remember goes like this:
5   5    3 4 5 5    4   3
No more talking high you oh
5   5    3 4 5 4   3   2
No more talking hey you oh
5   5    3 4 58 8    7 6 8
No more talking high you oh-o
5    3   1    3   2 2 1
Fare you well, my lady oh

No more walking ...

No more rowing...

I can't please you...

Guess I'll leave you...

and, I think
I still love you...
but perhaps that was my addition.

Thought it should go in here, anyway.
Blessings,
Barbara
