It's easy to check for spirituals in Mudcat's own African American Spirituals permathread, using the handy INDEX. In fact, there are two different threads for this song, both linked in that index.   (The index will soon be updated to include links to all the songs listed further down in the permathread.

There's another very similar song with a different tune, that was just posted HERE.

As to origin-- spirituals were created ad hoc and anonymously. The earliest versions in print are simply as collected by one or another transcriber. And there are still songs being transcribed into notation in our time, that were handed down orally from slavery times.

There are no "authoritative" versions of any one song, since a key aspect of the genre in its day was spontaneous versifying and/or the use of various commonly-used verses that could be dropped into just about any song. On the day a song was transcribed, one sees, frozen in time, what was sung on the day the song was collected. It's entirely possible that the singers may have felt some reluctance to to comply with a request for songs, and may have offered as little as would satisfy the song collector. So it might have been a very different song on another day. Also, often the songs were much longer than collected-- used as work songs all day in the field, one can assume additional verses popped into being. You are free to continue this tradition in our own time, and create verses yourself.
