Greg is right, it doesn't fit the tune of Chevy Chase. But I checked Speight's book and he quotes from a History of Preston(1822), possibly the source for the Harland quote above, since we have 'a buxom, handsome young woman.....gratifying her curiosity', but going on to say that 'it was the occasion of producing a ballad, which obtained as much notoriety in Ribblesdale as the famous historical ballad of 'Chevy Chase.' So it looks like a misreading/misremembering/mistake. But all the sources agree that only a short fragment of the old ballad has survived.
    Speight also quotes from Ray's History of the Rebellion(1749) the story in which a sergeant, Dickson, his mistress and a drum captured Manchester. Later she returned to Long Preston where the boldness of her exploit led to a the composition of a ballad. There's a great story in there waiting to get out.
