Re "Farewell to Lochaber":

James Anthony Gardner, Recollections, ([Ms. 1836;] (London: Navy Records Society, 1906), p. 5, ref. to 1775:

        “[Charley] Buchan [purser of HMS Boreas] got up and, flourishing the carving knife, sang with a voice of thunder, ‘Farewell to Lochaber,’ which made the landlord back out as if he had been at the levee.”
