Merrily We Roll Along, with music and lyrics by Stephen Sondheim and book by George Furth, is a musical about friendship and the compromise of youthful ideals, based on the 1934 play of the same name by George S. Kaufman and Moss Hart. Merrily We Roll Along begins in 1980 and moves backward in time, from 1980 - 1955, telling the story of three friends whose friendship is tested by time, events, ambition and fate. It charts the rise of a songwriting team during the years of Sondheim's own early career, and includes some of his most brilliant and bruising songs, including "Not a Day Goes By," "Old Friends," "Our Time" and "Opening Doors." Although unsuccessful in its original 1981 Broadway production (which ran 16 performances at the Alvin Theatre), Merrily has gained stature and reputation over the ensuing years, beginning with a reconfigured version at the La Jolla Playhouse in California in 1985, directed by frequent Sondheim collaborator James Lapine. Mr. Lapine will return to the project as director of the Encores! production.
