When you're the stage manager of a show, the cast and crew know that they should not come up and talk to you unless it's very important. The director of the current show lists two things as important enough to interrupt the stage manager: the theatre is on fire or there's a bone sticking out.
Tonight, the music director interrupted me to ask for a fire extinguisher. And it was for real.
There's something funky going on with one of the cords, and the amp caught on fire. Luckily, it got unplugged and moved to a safe place. The stage stank of smoke for the rest of the show, but, hey, it was small and we survived!
