Guest Gotariver, the N. O. jazz band version, often played in a kind of upbeat marching tempo, differing somewhat from the spiritual and protest versions, is related to the song posted far above, 2 Nov 04, "Gwine-a Study War No More," and the verse
Gwine-a lay down my burden
Down by de ribber side, .....
No idea how old this verse is, but it has been around a long time. The Hampton Institute students sang the verse in "I Ain't Goingt' Study War No More." See Dett, 1927, "Religious Folk-Songs of the Negro as Sung at the Hampton Institute," pp. 74-75 (with music). Not in the 1874 Fenner volume, but added in a later edition.

Thanks for mentioning the Sam Morgan recording.
One may hear it and other fine pieces on Red Hot Jazz: http://www.redhotjazz.com/SamMorgen.html; the second one on the Discography.
