"Da Galley Watch" is a Shetland reel in cut time and D Major. The parts are played ABB (Bain) or AABB (Anderson & Georgeson, Brody, Martin, Shuldham-Shaw).
It is a typical Shetland reel, known throughout the islands. It was collected and preserved by the Shetland Folk Society. Anderson & Georgeson (1970) note that there were many versions of this traditional tune, some known by other titles.
The sources for the notated version are Boys of the Lough [Brody] and John Stickle (1875-1957, Unst, Shetland) [Cooke, Shuldham-Shaw].
It was printed in Anderson & Georgeson's Da Mirrie Dancers (1970), Bain's 50 Fiddle Solos (1989), Brody's Fiddler's Fakebook (1983), Cooke's The Fiddle Tradition of the Shetland Isles (1986), Martin's Traditional Scottish Fiddling (2004) and Pat Shuldham Shaw's "A Shetland Fiddler and His Repertoire: John Stickle 1875-1957" in Journal of the English Folk Dance and Song Society, vol. 9, no. 3, Dec. 1962.
It was recorded by Tom Anderson and Aly Bain on The Silver Bow (1976) and Boys of the Lough on Second Album (1974).
