Well, that was fun!
For one thing, I don't know why I hadn't figured this out in advance, but there's more to HDTV than a great picture ... the sound is pretty amazing, too. So Lucinda and her band sounded excellent.
Beyond that, I can tell you what color her eyes are (green), how much makeup she wears (enough to hide at least some of her 50 years), where you can see all of the 50 years (her hands), how good her teeth are (not as good as mine). In other words, the picture was pretty astonishing. This was the best HD show I've seen since we got it last week.
