Now I believe in the separation of church and state as much as the founding fathers, but isn't this inability to perform "Ave Maria" at a public school event going a bit too far? And in my own state. And it wasn't even the sung version.
If you think about it, a large percentage of classical choral works is in some way or another sacred-based because it was created for the catholic mass. Can we no longer allow the high-school choral teacher to produce Mozart's requiem? Faure's Requiem? Verdi's Requiem? Do high-school kids no longer get to experience great music because it was originally intended for a religious service? The intent on performing it today is not to foist the meaning of the music (the mass) upon those listening, but rather to have them experience great music. I know I performed classical sacred music in high-school and that was not long ago (a mere 25 years now :)). It seems we've drawn the line too far.
