YES. PLEASE. Years ago I saw the show in London, where it had been running forever too. I was looking at an actress for a show I was producing. It was a matinee. There were less than 200 people in theatre. I learned that sales were often dreadful, but that the show was kept running as it was the showcase for creating tour and sit downs all over the world - a giant shop window for the CHICAGO brand. Wow then. Wow now. Let it go.
