I don't have it but I remeber a Folkways record with Libba Cotten singing the verses above. Nobody, thank the Goddess, has written additional verses as has happend to Freight Train. I suspect Libba's estate owns the copyright-- Mike or Peggy Seeger would know I bet! (It is also possible that Folkways Records, now Smithsonian Institution, owns the copyright!) As Gilbert and Sullvan would say-- topsy-turvy!
