I am all about the kids learning to sing (or play) on key and in tune. I fully recognize that it takes training, practice, and some more practice (and then some more training).

I also applaud their willingness to show what they can do. I remember doing such things when I was that age, though, and for me at least it was simply part of the normal routine of being in band--we played in public. We didn't much have to concern ourselves with whether people in the audience had perfect pitch. That was the director's job.

And, as I tried to mention, I was impressed at the skill levels shown. "Only cringed a few times" is really quite a compliment from me--I often avoid such things entirely for fear that I wouldn't be able to "uncringe."
