I think the text of Simple Gifts which I translated into Esperanto for my hymnal is a Shaker text. Here are both the English and my translation. Contemporary published sources for the English text include the Episcopal Church's Hymnal 1982 and the Disciples of Christ Chalice Hymnal.

Incidentally, this thread (which I hadn't seen before) includes a lot of info about the tune that I hadn't known before.

Another Carter hymn that I really like, and whose tune I think has got to have folk roots (even though I don't know and of course the Stainer & Bell folks claim he wrote it) is Said Judas to Mary, in the United Church of Christ's New Century Hymnal.
