Coco was a 1969 Broadway musical with a book and lyrics by Alan Jay Lerner and music by André Previn, inspired by the life of Coco Chanel. It starred Katharine Hepburn in her only stage musical. Background Theatre producer Frederick Brisson originally had optioned Chanel's life for his wife Rosalind Russell, but Russell had developed acute arthritis, making it difficult for her to function. That meant another leading lady with star quality needed to be found. Irene Selznick suggested Katharine Hepburn, who initially scoffed at the idea of appearing in a musical but agreed to work with former MGM vocal coach Roger Edens for ten days. Following an audition in Selznick's suite at The Pierre Hotel, Hepburn felt comfortable enough to mull seriously the proposition, and was further convinced to accept the offer after meeting Chanel.

Danielle Darrieux replaced Hepburn eight months into the run, but without the drawing power of a major star the poorly reviewed show closed two months later. Hepburn was scheduled to star in a West End production, but when the Theatre Royal, Drury Lane proved to
