My mother used to sing this to me (in New Brunswick Canada during the 50's. She was born in 1907. Her version went like this:

Down in teh canebrake close beside the mill
There lives a little yeller girl
Her name is Nancy Till.
I love my Nancy I love her long
I'm going to serenade her I'll sing her this song.

Come love Come
the boat lies low
It lies high and dry on the Ohio.
Come love come
Won't you come along with me,
And I'll take you down to Tennessee.

Open your window love oh do
And listen to the music
I'm playing for you.
dah dah dah dah (forgotten words by mother)
and in a trundle bed
There'll be a little pickanin
when all the prayers are said.

Chorus again.
