Kenneth Caillat and Steven Stiefel, co-authors of the memoir Making Rumours: The Inside Story of the Classic Fleetwood Mac Album, have filed a lawsuit in the U.S. District Court for the Southern District of New York against playwright David Adjmi, along with the producers of Stereophonic. The plaintiffs claim that the Tony Award-winning play is an unauthorized adaptation of their copyrighted memoir.
According to the lawsuit, Stereophonic has grossed over $20 million since opening in April 2024 and was promoted as "The Most Tony-Nominated Play of All Time," winning five Tony Awards, including Best Play. The plaintiffs allege that the show’s success was built on material taken from their memoir without permission, asserting that Stereophonic is "substantially similar" to Making Rumours.
