This Old World (anon., arr. 2020) 

A fairly simple, practical arrangement of this folksong/hymn first published in The Southern Harmony of 1835 (as Mercy, O Thou Son of David). Both melody and text are of uncertain authorship and seem related to a number of similar tunes and texts. The text here is the one found in the Unitarian-Universalist hymnal Singing the Living Tradition, #315. $2/copy, minimum 8 copies (6 pages each); order here.
