Sean: The version i have on CD by the Second South Carolina String Band Also mentions the Morphia addiction. It is my understanding that the tune was originally a Scottish fiddle tune that was adapted to a march sometime previous to the American Civil War and probably before the Mexican War. Other than that anytyhing I have is sketchy at best. It's a great song. I play it at encampments and the crowd seems to like it. Good luck in your search. Kindst reguards. Neil
