One problem is that this year, they were looking to be a cape short, and because it had been almost six years since this song has been performed, there was a significant amount of concern regarding exactly who would be allowed to 'cape up'.
One of the more senior girls explained that since the older choristers had been given precedence last time, and this had left her out, this meant a) she was going to wear a cape, b) the other high school girls should be wearing them as well, and c) one of the junior high girls should do the right thing, and volunteer to go capeless, since there weren't enough to go around, and they would be likely to get another chance anyways.
Sure enough, one of the younger singers said, "okay, I'll do it", and was widely lauded by the others for her selflessness.
However, this did not prevent her from breaking into tears later, presumably once she realized that it might be another six years before the capes came back into rotation, if they did at all!
Thankfully, a piece of similar material was found, and no one in the audience was cognizant of the fact that a dozen girls wore capes, while the thirteenth was wrapped in a shawl. The video is below, but here is the link in case the embedding is problematic: http://youtu.be/Wbwzy8RlHgs
The iPad takes pretty crappy video in low light, and I doubt you will be able to distinguish Fenya (she is front row, second from the right), but the song itself comes through nice and clearly, and that is the most important bit, capes or no capes.
