*Just in Time* is a jukebox musical that traces the life and career of American singer Bobby Darin, using his songs as the spine of the narrative. It is currently running at Broadway’s Circle in the Square Theatre, staged in the round, a format that can make Darin’s public persona feel unusually close and scrutinized. With a book by Warren Leight and Isaac Oliver, the show treats mid-century pop as a window onto New York’s entertainment machinery. It lands as both biography and a study of how celebrity gets built.
