Thankyou both of you. I now have at least three versions of the words. I'm still worried about the tune though.

I remember a record of a group called Gryphon (that I borrowed from my brother years ago) and it had the same odd number of verses. As I said, it has been set to a tune RVW calles Kingsfold (see English Hymnal). However, that requires two lots of 4 lines per verse. See my problem. Is it that the song is actually incomplete, and has been sung with an unfinished last verse for years, or is there another tune of which anyone knows.

Cheers.
