I've been cruising hymnals and gospel music sites for the last two years and I always look at this item when I come across it. I have never seen or heard any additional verses or significant variants, other than as noted above. Not to say they aren't out there-- but I would not know where else to look, because it feels like I have been everywghere and back again! ("You have come to the end of the Internet. Please turn around, and go back.")*G*
But if I ever DO find anything new I will sure post it here.
