Listened to this today and thought it was a pretty good interview (isn't it usually with Terry Gross, though).
The he one thing that popped out to me was when he was talking about how the Palace, St. James and Imperial will be closing for extended periods soon. The Palace, of course, to be raised, the St James so the stage can be extended for Frozen, and the Imperial because a new theatre is being built next door. But what happens if The Great Comet becomes a hit? Are they aware that the theatre owners are planning to close their theatre at some point?
