Looking for:
1. Words actually put to the song by Sir Hugh Roberton in 1938.
2. Bona fide words to a pre-Roberton and/or traditional version. Is there such?

3. Tune:
a. The Tinkers say it is a "traditional air from region of Loch Treig."
b. The Corries say the tune is Creag Guanach
c. Barry Taylor says the tune is Lochaber.
Are these all the same?

Looked through a lot of websites and all three threads without finding definite answers. For a fairly recent song (20th c.) there is a hell of a lot of unsupported speculation.
There are almost as many versions of the lyrics as there are singers (almost everybody). About half the websites say the song is traditional, another 40 percent fail to indicate, and perhaps 10 percent correctly credit Roberton.

Note: Enough already on the Minch. I intend to have homemade minch pie at Christmas with plum pudding on the side.

Going through the websites, the first line of the chorus is started variously
Heel you (ya) ho
Neil you (ya) ho
Hill you (ya) ho
Heil ya ho
Any others?

Would like to know what the McCalmans mean by "Not a wave in straights and narrows." They give outbound sailing directions- "out by Uist and by Lewis as the sun sets on Mingulay." Geographically valid?
