A few years ago I was playing in the pit for Beauty and the Beast. During a scene, one of the supporting actresses was wearing a body mic. When she left the stage, the soundboard person didn't fade her mic. Obviously the tech crew backstage didn't turn off the body mic, either, because the entire audience could still hear her talking backstage. We were then treated to about a half minute of her talking to someone about how she should have gotten the role of "Belle" (the lead role) and that she was a much better actress than the girl who got the part. All this while the next scene was continuing on stage. While it was fascinating in its own bizarre way, I wanted to crawl into a hole, because it was so embarrassing for the entire company. And where were the sound people? They obviously had no idea what was going on. Absolutely unbelievable.
