Actually, Bruce, Frank Proffitt did know two versions of the ballad -- the "Gyps of David" version that he learned from his aunt, Nancy Prather, and the more common "Black Jack Davey" that he learned from other folk in his Appalachian community. I think Lawrence had only the one version, using the "Rattle lattle lingo lingo ling" chorus. Is that the one you say resembles the Wisconsin version your ex-mother-in-law sang? It's a fun one to sing.
