33? What, is this a specific group singing it or something, that makes it difficult? Otherwise-- well, it's a good hymn. "Open my eyes that I may see... Glimpses of truth... Thou hast for me..." etc.

The Unitarian Church does have different words for it, so that's not the way I learned it, but I've sung it enough to know some of the various variations.

I'll probably come back to this and guess some more when I'm not at work.
