"Nimrod Workman (November 5, 1895 - November 26, 1994) was an American singer, coal miner and trade unionist. His musical repertoire included traditional English and Scottish ballads, Appalachian folk songs and original compositions. . . . Throughout his coal mining career he was active in union politics and United Mine Workers of America organizing. In 1920-1921 he worked alongside Mary Harris "Mother" Jones in West Virginia, and participated in the Battle of Blair Mountain uprising. In later years he advocated on behalf of black lung victims, and was able to receive union compensation for his own health problems in 1971." - http://en.wikipedia.org/wiki... - mkz
