Correct me if I am wrong since I don't know London geography that well. But, I remember reading online someone's opinion that the reason why Movin' Out didn't do so well in London was due to the fact that the show was placed at the Apollo Victoria which isn't really in the center of things so that no one would actually see it and know that it is around. Also, they suggested that possibly one of the reasons why it didn't do so well there is that it has been years since Billy Joel has done a tour let alone a concert in England.
As for Dirty Dancing, I remember seeing the show for a second time in Boston. During that time they were collecting for Broadway Cares. I knew that not that long before I went to see the show again, rumors of the show taking the Neil Simon came to surface. I kind of figured that they were almost done with their long stop in Boston and then moving to LA where they are going to have their final stop of the tour that they must know something about the future of the show on Broadway.
I had asked a couple of different cast members and they said the same thing. They had said that plans for Broadway had been pushed aside and that this production is going to shut down after they are done in LA. I must say that it doesn't matter if you like the show or not. But, it seems to me to be a bad move on the side of the producers. That they have this show that is an international money maker and making money on tour in America. You would think that they would be smart enough to bring it to Broadway where it can continue to make them more and more money.
