The song you're discussing here appears as "Kishmul's Galley" in the first volume of "Songs of the Hebrides" by Marjorie Kennedy-Fraser (published circa 1905). Kenneth MacKellar recorded it about 1960 for "Songs of the Hebrides", an album of Kennedy-Fraser songs with commentary delivered over a background of surf-and-gulls noises.

The Kennedy-Fraser arrangement thunders like Wagner, but it's a thrilling ride when both vocalist and accompanist are equal to the considerable demands of this noble song.
