If you read J. Lomax's 1941 book you'll come away believing that the (unusual, in the second line) stanza

If I feels tomorrow like I feels today
Take a long freight train with a red caboose to carry my blues away

was sung by Enoch Brown.

He wrote a 1939 article that said this stanza was from John Wesley Gordon, who hadn't been discovered by Howard Odum until the mid-'20s.

His 1917 article filed this stanza under a blues attributed to the female singer "Dink."
