The musical Sunday in the Park with George has been the subject of speculation ever since it opened in 1984. Some say its story reflects the life and struggles of its composer-lyricist Stephen Sondheim, and others celebrate how the unknown writer and director James Lapine steered Sondheim's work towards new vitality. James Lapine has now written a detailed and candid account of the show's fabled journey. It's called Putting It Together: How Stephen Sondheim and I Made Sunday in the Park with George (Pan Macmillan).
