Opened in September 1923. Ran 68 performances, to about October 1923. A Moon for the Misbegotten is a play in four acts by Eugene O'Neill. The play is a sequel to O'Neill's Long Day's Journey into Night, with the Jim Tyrone character as an older version of Jamie Tyrone. He began drafting the play late in 1941, set it aside after a few months and returned to it a year later, completing the text in 1943 – his final work, as his failing health made it physically impossible for him to write. The play premiered on Broadway in 1957 and has had four Broadway revivals, plus a West End engagement. Wiki link
