The Jay-Z produced Broadway musical Fela!—which took home 3 awards at this year's Tonys—is based on the life of Fela Kuti... problem is, it may also be based on a book about the life of Fela Kuti. Reportedly the author of the book Fela Fela: Cette Putain de Vi, Charles Moore, is demanding that performances of the musical stop on Monday.

Years ago Moore was offered $4,000 for the rights to turn his work into a musical, but he rejected the offer; he now claims the writers of the musical copied entire sections from his book verbatim. He filed a lawsuit in U.S. District Court in Manhattan this week, and is seeking a minimum of $5MM in damages, a halt to advertising, promotions, and product sales resulting from the show. Fela Kuti personally requested that Moore write his life story, just before he died, and the writer was given access to his friends, family, and personal files—something the writer's of the musical could have only gotten from his book.

Meanwhile, a spokesman for the show says he's "really shocked" because Moore (who claims his book is the only authorized biography of the composer, singer, musician and political activist) appears on the show's website promoting the show.
