My fairly extensive collection of hymnals is, unfortunately, overwhelmingly American in its English-language contents; the only British English hymnal I own is the animal-rights collection Hymns for Creatures Great and Small, from which I took the text; it is a text-only collection.
So I'm wondering, hopefully, if some British Mudcatter has this tune and can post it or email it to me in some usable format (preferably PDF or MIDI, or NWC)...
