One last, minor addition. I went back and listened to the Watson Family recording, and there are a couple of minor differences:

In the second verse, it's "My soul will rejoice BY the crystal river," not "in."

In the third verse, it's "Because TO the Lord, I have made cofession," instead of "of" the Lord.

And also, in the third verse, it's "But now on my soul there is no transgression," Instead of "From" now.
