State Fair (1945) (aka It Happened One Summer)

In this Richard Rodgers' and Oscar Hammerstein II's filmed musical by co-directors Jose Ferrer and Walter Lang:

• the show-stopping opening number "Our State Fair", sung after the opening title credits, (with each verse rotated through and sung by members of the Frake family, in a fake farm setting): "Our State Fair is a great State Fair..."
• the lovely, long curly-haired, teen-aged ingenue Margy Frake's (Jeanne Crain) longings for love, and the scene of her packing in her bedroom for the fair - performing the Best Song Oscar-winning "It Might As Well Be Spring"
• her first meeting with suave, fast-talking newspaper reporter Pat Gilbert (Dana Andrews)
• the oft-repeated "It's a Grand Night for Singing" - a lilting love song, first sung on stage by a band, and then passed from one couple to another at the Iowa fairgrounds - on the merry-go-round and on other carnival rides
• their subsequent three-day romance
