I assume they have to get permission from MTI. Music Theatre International does have people that go to different shows and make sure that particular theater company is performing the show legally and only making changes that are legal.
That is patently false and just flat out wrong.
No licensing agency, MTI or otherwise, randomly sends representatives to productions in the nearby area to "make sure" of anything. They only investigate a production or licensee if a formal complaint is filed, and they only pursue further action against the licensee if said investigation provides evidence of a violation or at the official request of an MTI author and/or their controlling estate.
