No useful help, but there were many protest songs written by women of Harlan County and the other coal-mining areas of the Appalachians- Sarah Gunning, Hazel Dickens, Florence Reece (wrote "Which side are you on") and others. Could have been by one of them. The strike against the Duke mining company was long and bloody; the songs that arose out of Harlan were rewritten to apply to the Empire mines in New Mexico, Lothian strike, and elsewhere.
