Sounds like great news. I love Walken. It's good to hear things are going well. Good luck with it all. Don't be so down on the human voice, it can be the most fragile and devastating instrument to our imperfect ears. Also remember what Philip K. Dick said when dealing with words:

"I've always told people that for each person there is a sentence - a series of words - which has the power to destroy him. Years later I realized that another sentence exists, another series of words, which will heal  the person. If you're lucky you will get the second; but you can be certain of getting the first; that's the way it works."

To some extent it seems the songwriter, whether consciously or not, is always searching for the second. Maybe not finding the series of words that heals him but in the process of his travails he may unintentionally heal someone else. I suppose it's always possible he could deliver the first sentence too. In any event there is good reason to continue searching for the words, what you find may be someone's antidote. Now carry on...
