I for one, found Tolkien's voice far more 'mystical' than
all of the actors in the films. It sounded like he could actually use the language in day to day life (seeing he was fluent in both the elven languages and finnish, he could!) unlike most of the actors who seemed to almost sing the words, which quite frankly is im-bloody-practical... and as for "english accents making the words sound icky" i shall (like squatter [i am so proud of your restraint!]) stop myself from speaking openly, for one could say exactly the same about american accents!
May I say, however, how much I admire Joy for the time and effort she has obviously poured into her endeavour of learning such a difficult language. My hat and heart goes off and out to you.
Keep up the work, and i am sure you'll have it flowing as you say you'd like!!
