Should Mount Scopus hire out its theatre on Shabbos?

Received from AG:
I noticed the following advertisement in today's Sunday Age. I have no idea if it is halachically permissible for Mount Scopus to hire out, or even give free of charge, its Besen Centre theatre for a Friday evening performance. But in my view it looks terrible that a Jewish school, especially one that is officially more or less Orthodox to do so. I would think there would also be “maris ayin” issues. It would be important to hear the views of the Melbourne rabbinate. Maybe Rabbi Kennard (who no doubt would have been against this) could place this on the agenda for the next RCV meeting.
