Problem: Carousel is the second musical by the team of Richard Rodgers (music) and Oscar Hammerstein II (book and lyrics). The 1945 work was adapted from Ferenc Molnar's 1909 play Liliom, transplanting its Budapest setting to the Maine coastline. The story revolves around carousel barker Billy Bigelow, whose romance with millworker Julie Jordan comes at the price of both their jobs. He participates in a robbery to provide for Julie and their unborn child; after it goes tragically wrong, he is given a chance to make things right.

Two young female millworkers in 1873 Maine visit the town's carousel after work. One of them, Julie Jordan, attracts the attention of the barker, Billy Bigelow ("The Carousel Waltz"). When Julie lets Billy put his arm around her during the ride, Mrs. Mullin, the widowed owner of the carousel, tells Julie never to return. Julie and her friend, Carrie Pipperidge, argue with Mrs. Mullin. Billy arrives and, seeing that Mrs. Mullin is jealous, mocks her; he is fired from his job. Billy, unconcerned, invites Julie to join him for a drink. As he goes to get his belongings, Carrie presses Julie about her feelings toward him, but Julie is evasive ("You're a Queer One, Julie Jordan"). Carrie has a beau too, fisherman Enoch Snow ("(When I Marry) Mister Snow"), to whom she is newly engaged. Billy returns for Julie as the departing Carrie warns that staying out late means the loss of Julie's job. Mr. Bascombe, owner of the mill, happens by along with a policeman, and offers to escort Julie to her home, but she refuses and is fired. Left alone, she and Billy talk about what life might be like if they were in love, but neither quite confesses to the growing attraction they feel for each other ("If I Loved You").  Over a month passes, and preparations for the summer clambake are under way ("June Is Bustin' Out All Over"). Julie and Billy, now married, live at Julie's cousin Nettie's spa. Julie confides in Carrie that Billy, frustrated over being unemployed, hit her. Carrie has happier news--she is engaged to Enoch, who enters as she discusses him ("(When I Marry) Mister Snow (reprise))". Billy arrives with his ne'er-do-well whaler friend, Jigger. The former barker is openly rude to Enoch and Julie, then leaves with Jigger, followed by a distraught Julie. Enoch tells Carrie that he expects to become rich selling herring and to have a large family, larger perhaps than Carrie is comfortable having ("When the Children Are Asleep").  Jigger and his shipmates, joined by Billy, then sing about life on the sea ("Blow High, Blow Low"). The whaler tries to recruit Billy to help with a robbery, but Billy declines, as the victim--Julie's former boss, Mr. Bascombe--might have to be killed. Mrs. Mullin enters and tries to tempt Billy back to the carousel (and to her). He would have to abandon Julie; a married barker cannot evoke the same sexual tension as one who is single. Billy reluctantly mulls it over as Julie arrives and the others leave. She tells him that she is pregnant, and Billy is overwhelmed with happiness, ending all thoughts of returning to the carousel. Once alone, Billy imagines the fun he will have with Bill Jr.--until he realizes that his child might be a girl, and reflects soberly that "you've got to be a father to a girl" ("Soliloquy"). Determined to provide financially for his future child, whatever the means, Billy decides to be Jigger's accomplice.  The whole town leaves for the clambake. Billy, who had earlier refused to go, agrees to join in, to Julie's delight, as he realizes that being seen at the clambake is integral to his and Jigger's alibi ("Act I Finale").
