I happened to be staying at Macquarie University in Sydney that week, doing a choral composition course thingy, where there were over 300 choristers in 4 choirs. That day we were given an hour to write a piece for the treble choir and an hour to workshop it; I spent about 10 minutes writing it and the choir took care of most of the workshop. Great experience. It was very handy having this text here. I even put your name on the score.
