Placido Domingo was conducting a production. One particular performance fell on Halloween, and a few of us felt an obligation to be a bit festive. Sticking to our all black dress code, this was the result. Placido came into the pit for his opening bow and had to pass by Elvira (assistant Concertmaster), in order to climb onto the podium. Well, he had such fun playing with Elvira’s hair that management noticed the delay, and we were summarily informed at intermission that there were to be no costume elements of any kind in the pit. Boo!
