Okay, I refuse to dip more than a toe into this one because it really is not worth it, but I do want to address the "sound department" perceptions here and accusing someone of not knowing names.
1. He said "sound department", which can refer to people AND the equipment / automation. It's a collective term. He didn't say the sound board op screwed up.
2. As said before, had he posted a name, you'd be nailing him to a cross for saying a name, even jokingly.. Mind you, no one here says a THING when an actor tweets or mentions in an interview a fellow actor bitching a scene and having a mishap.
3. Maybe he didn't know the name. Doesn't mean he doesn't know the names of people in the sound department. In a long running show, there are multiple sound board operators, multiple deck audio people, and no, actors do not always cross paths with them in the building during the course of a show. THAT MEANS THEY ARE DOING THEIR JOBS. Orchestra members arrive last and often go straight to the pit and leave straight after, and there are many subs, so many in the building... Crew members have lengthy pre-sets o do before the house opens and things to do leading up to curtain, a tors are warming up and dressing... Unless you DIRECTLY deal with someone during a performance, you may not often communicTe with someone or see them at all on no given day, so you may not even be aware that a crew member is out or who the sub is..
