The movie version is, [studying].
Also, [robe and crown] alternates with [starry crown].
The verse order in that version is sisters, brothers, fathers, mothers, sinners. But like Mississippi John Hurt's "Blessed Be the Name," the exhortation can be directed to any group. It sounds, on the tape, like each group called to joins in on the next repeat of the chorus till all are in, but I am not sure and have not seen the movie. That's how I'd do it with a large group though, as a song-led piece.
My tape is out in the car, froze, and I don't wanna play it froze and break it, but my recollection is that some sections are [down TO the river to pray] and some are [down IN the river].
The verses end, I think, [Godd Lord, show me the way.]
Lovely on autoharp in C.
Apply folk process and mix well. Serve hot.
