AMN-I am a cast member of this production. Yes, Cameron is coming to see us in Atlanta,and he visited us during rehearsals in New York, however it's not as cut and dry as you say in your post.
This is a new staging of the show, with a new set, and no turntable. We use some, but not all of the broadway props and furniture as well. It is staged by Fred Hanson, who was the executive producer of the revival as well as a long time associate director of the piece and one of the original stage managers going back to 1987. Fred has staged many other of Cameron's shows (most notably major productions of Miss Saigon here in the US as well as Japan) It is musical directed by Dan Riddle, who oversaw the Tenth anniversary company in New York, as well as conducting the Marius Company on the road for many years. The Set was designed by John Napier's Assistant, in the original Les Mis style, although its much different in execution. We travel with our own floor, but it is not automated. Plus there is heavy use of projections.
That being said, it isn't as simple as Cameron coming to Atlanta and this production turning into a tour(even though this particular production has been very successful in terms of ticket sales). It really is more of a case of Cameron seeing the show in this new staging and seeing if it works. He is very protective of the show (he is actually listed as a producer of this production) and as far as i know is really coming to see the show done without a Turntable.
This particular show (because of the huge venues we are playing) is massive in its size, and there really aren't many theaters around the country that could hold us.
Also, a national Tour would have to be booked way in advance, so we're talking about at least 2010 till a tour really could be put together.
Other than that, did you enjoy the play Mrs Lincoln?
