The Thomas Haweis hymn posted by Joe obviously is the source hymn, not the Crosby-Perkins one which I posted.

The first verse appears in Black folk collections going back to 1900, so Willie Johnson would have been aware of versions of the hymn.

The 'Richmond' tune given at the site used by Joe is an arrangement by Martin Shaw; it seems to differ from the one in "The Bristol Tune-Book, a Manual of Tunes and Chants" (pub. Novello et al., London, c. 1890).
