I have gone back over all of the "Shenandoah" threads and discussions and I did not find this version anywhere. It is from W. Roy MacKenzie's BALLADS AND SEA SONGS FROM NOVA SCOTA,(Harvard University Press, 1928)p. 270, with the tune on p. 402. MacKenzie says it is "from the singing of Ephraim Langille, Tatamagouche, Colchester County, [Nova Scotia]."

             "Rolling River"

O if I had a dog I would call him Hunter,
Hooray, my rolling river!
O if I had a dog I would call him Hunter,
I'm bound away on the wild Missouri!

And every roll her topsails shiver,
Hooray, my rolling river!
And every roll her topsails shiver,
I'm bound away on the wild Missouri!

MacKenzie says that "this is a windlass and capstan shanty,..." T.O.M.
