The Lomax notes, as with many of the songs, are incomplete and sometimes incorrect.
All of the verses of the two versions are incorporated in the first posting, except "Singing come home," which I missed but you caught. Sometimes "Soon one morning" is sung rather than "One morning soon," and this verse is sung twice in one of the versions. The verse "All in my room" is varied in the recording with Allison leading- He leads off with "All 'round my bedside," but then they sing "All 'round my room." He also slightly changes pace, interjecting "My Lawd" in the middle of each first line.
This song should be one of the first to receive a midi. It is simple, and very catchy.
The Lydia Parrish version (Masato, above) must have a somewhat different tune; I have trouble fitting the first line of the verses to the tune used by Vera Hall et. al. I haven't heard the recording. Most of the words published by Arnold fit, but I would guess that there is a tune variation here as well. This is something I have noted with older cowboy songs as well; the tune, if the music is given, varies somewhat from collection to collection. This would be expected with all songs that are transmitted verbally.
The Hampton version is more complex, but belongs here, and shows that this cluster of spirituals has been sung for a long time.
