Thanks JohnThere is a ballad "Thurot's Defeat" on the Bodley Ballads website. The ballad has no tune direction. There are two more in Gilbert Hay of Minto's MSS in NLS (MS 12820) the first, "Thurot's Defeat" by Peter Nittle to the tune of "To all ye ladies now at land", and commences "When Lewis & his Pompacour". The 2nd is evidently by Gilbert Hay, himself, and is entitled "A Song to the tune of Moll Roe" (this is 15 years before the publication of the tune), commencing "The French thought long to invade us".
