When you are granted a performance license, by law, the show you license must be performed, "as is." You have no right to make any changes at all unless you have obtained prior written permission from MTI to do so. Otherwise, any changes violate the authors’ rights under federal copyright law. Without prior permission from MTI, your actions may subject you to liability - not only to the authors, but also to us - for breaching the terms of your license agreement, which clearly forbids you to make any changes or deletions.
