"The Factor's Song" would be a good choice. We recently transcribed a version from Maine that runs 53 verses collected by Marguerite Olney on Sept 20 1941 for the Helen Hartness Flanders collection. It took Nelson Powers of Mattawamkeag, ME 37 minutes to sing it. Flanders published it in her book "Ballads Migrant in New England" pp 154-162
