In Days of Wine and Roses, the new musical based on JP Miller’s 1958 teleplay and Blake Edwards’s 1962 Warner Bros. film, the central characters introduce themselves in song as “two people stranded at sea.” Even when offered lifelines, as the boozy, destructive duo often are, they respond like drowning victims, clawing and scratching, threatening to bring their rescuers down with them. With a book by Craig Lucas and a score by Adam Guettel, Days of Wine and Roses presents a searing and sobering portrait of the devastating costs of addiction.
