I found this: Far Above Cayuga's Waters ~~ Lyrics written by Weeks and Smith (circa 1875) to the tune of an existing song Annie Lisle. Annie Lisle was written by a Boston musician H. S. Thompson in 1857. That may be a lead, possibly someone at Cornell knows more.

Don't know if you located it or not, but UNC Chapel Hill has a copy of Lily Dale at http://cadmus.lib.unc.edu/music/white1/white1.htm It is superior in quality to the Levy files, but a whole lot harder to find.
