I was always intrigued with the tune, how it shifted from one key to another between lines of the verse, and how it s-t-r-e-t-c-h-e-d out as you sing "a-n-d I c-o-u-r-t-e-d a f-a-i-r y-o-u-n-g m-a-i-d-e-n, Nancy was her name." I was also intrigued by the miscellaneous verses that were aggregated in this song. Certainly is unique.
