I thought that as no-one has answered, I'd post what I found out before this question disappears off the page (which isn't much). It appears as if Ms. Morrell is still campaigning for human rights - she has a book/pamphlet about unjustly imprisoned people, and has to have taken part in some educational videos on the subject. She and John McC split up about four years after his release, and he is now married to someone else. From an interview in the Guardian, it doesn't sound as if he and Ms. Morrell keep in touch much. Sorry, best I could do. There was a site that claimed to have contact details for celebrities that listed her, but I didn't fancy signing/paying up. (Not to mention that some of the people they listed - L.Ron Hubbard, for instance - could only be contacted via a medium).
