BYU choirs are very interesting things. If you ever go to choir practice, there are usually at most 10 people there. Choir directors are always begging more people to come. And usually the people who come (at least the men) really can't sing. I've tried to participate in several BYU choirs, but I just get frustrated because there are only 3 bass singers (including me), and I'm the only one who seems to realize whether or not you've hit the right note.
The thing is, anytime a BYU choir is asked to sing, sometimes it seems like half the ward stands up. Like 50 or more people. Yes, that's right - there are "choir members" who really only go to choir practice maybe once (if that), and then sing with the choir in church. It is the weirdest thing. Some BYU students just consider themselves special. I had a roommate once who said if he was ever choir director, he would put pauses in weird places to make all those people stick out and never do it again.
