I had no idea we had begun talking about two distinct songs. Shouldn't have been surprised ~ it is certainly not unprecedented for two different songs to have similar names, especially when the name is a person's name.

I vaguely remember "Little Liza Jane" as a sort of children's folksong from when I was a child myself, and also encountered the same song in the pages of Sing Out! when I was a teenager. In both cases, it was the same song I would hear years later (in much livlier brass-band street-parade arrangements) as a young adult new to New Orleans. Also, of course, it certainly seems to be the same song mentioned in the original post to this thread ("I got a girl in Baltimore / L'il Liza Jane..." etc.)

If I have ever heard "Good Bye Liza Jane," I failed to remember anything about it. Now I'm curious!
