Jean Anouilh ballet librettos? in General Reading and Literature Posted January 14, 2005 Hi. I've been looking for a book or collection of the ballet librettos by the French playwright Jean Anouilh. He wrote several ballets for Roland Petit, including Les Demoiselles de la Nuit (The Ladies of Midnight) and Le Loup (The Wolf). I've searched online and in several major and used bookstores, but no results. Thanks.
