No one knows for sure why it’s called the green room. There is a theory that in 1599, London’s Blackfriars Theatre included a room where actors waited to go on stage, and it was painted green. I have waited in many green rooms. I have waited in theatre green rooms, pre-speech green rooms, and green rooms for TV shows. Once I waited in a green room for the Sally Jesse Raphael show. Yes, way back when. A few years ago I wrote a book about waiting in green rooms. I didn’t know it at the time, but recently I realized the habit of waiting is all about green rooms. It’s not necessarily a bad thing.
