Oh, how things have changed since I was in High School! In various years, I sang both the Schubert and the Bach-Gounod Ave Maria, and the sublime Gesu Bambino, by Pietro Alessandro Yon at the annual Christmas Assembly. [This in a Massachusetts public high school. Those days are gone forever.]
I was in very good voice then. Now, I don't sing at all, except when I'm doing the dishes!
