My guess, from previous posts, is noisy filiments in the stage and houselighting. Depending on when the hall last upgraded their lighting control system, they may have an early SCR controlled dimming system, with either insufficient, or no inductors in each of the dimming circuits. It's amazing the noise a hundred or so filiment based stage lamps will make, at certain levels of dimming, without the proper inductor in every lamp circuit. They really buzz and sing.
