I'd guess George is the semi-official keeper of the lyrics now...we can ask about and see if we are all still honoring Mary's request to spread it only by 'oral tradition'. Once words are posed openly, thousands of people can be messing with it....much like "You can't be a pirate with all of your parts".... but of course, every 'author' runs into that. Once a song is in anyway public, it takes on a life of its own.

   We who knew Mary can ask around and see what current thinking is.
