Is a concert at a school considered an exception to a curfew?

I did find the City of Tulsa Oklahoma Municipal Code Penal Code Chapter 28 Curfew Hours for Juveniles. Curfew starts at midnight on Friday and Saturday and is 11 pm the other nights. It is illegal for a juvenile to be out on the street or in a for-profit private establishment during those hours. The common areas of schools are considered public places. There are 9 defenses, including " 7. Attending, going to or returning home, without any detour or stop, from an official school, religious, or other recreational activity supervised by adults or an event sponsored by the City of Tulsa, a civic organization or another similar entity that takes responsibility for the juvenile."
