It was a production issue. The final weight of the (overhead) equipment was more than our ceiling.

We are disappointed that we will not be able to present this special concert at our facility, but we need to understand our limitations and ensure public safety.

It's unfortunate that this whole thing had to occur. I really hope this doesn't affect the school in a negative way.

After extensively reviewing the situation, all parties mutually agreed that cancellation of the concert was the only viable option.
