I gotta say, I saw this thread, clicked on the link, and before the video played my brain did that thing where a million "what ifs" swim through your mind. "What if it's not good... I can't in good conscience lie, but I simply don't have it in my heart to tell the truth if it's bad, I'll have to simply not post, either way I'll feel kinda sucky about it"
Then the video loaded and I was very relieved. It's good, excellent in fact. With more practice it'll probably be even better, but even just at this point, I would not have found it unusual sounding for a 60 year old woman.
So congrats, it's great.
