It's a long shot, but I have sent an e-mail to one Shannon Tinnell, who made a documentary in 2009 about the tornado, called "When the Wind Stole the River," in the event she might have run across the song in her research, or might at least be able to provide additional leads.

I am amazed that this thread is the first time I have ever heard of this eastern Tornado outbreak that also impacted a number of other counties in WV.
