George Furth and Stephen Sondheim's Merrily We Roll Along tells the story of how a composer's idealism and friendships were corrupted by success. It's told backwards, starting with the disillusioned present and ending with their optimistic college years.

The original production opened November 16, 1981, at the Alvin Theatre (now the Neil Simon Theatre). The revival opened at the Hudson Theatre on October 10, 2023, and extended its limited run through July 7, 2024.
