I can tell Brooklyn Tab music, too. It hurts to sing after a while. All of the men's parts seem to start above the staff, and go higher from there. They must really have something against basses up there, judging from the way they arrange their music.
Did you know that they do not have music to learn songs from? They start to memorize it as soon as they start learning a song. Or, that was the case when our old choir director went up there.
