Here's soem info on "My Long Tail Blue:"

Much of the music that was performed by the blackface performers contained melodies that had orignated in Britain. Some examples of these melodies and their origins include such songs as "Jim Crow," which resembled an Irish fok tune and an English stage song; "My Long Tail Blue," which had a melody similar to a Scottish folk song; and "Gumbo Chaff," which had a melody identical to that of an English song called "Bow Wow Wow."

Anyone come up with the lyrics?
