The film centres around a Will-they won't-they romance. Wealthy Jack Cromwell from Long Island runs off to New York City on account of his fiancee's relentless flirting. He attends an Independence Dayblock party where Molly Carr, from Yorkville, Manhattan, falls in love with him. Comic relief is provided by grocer Eric Swenson, above whose shop Molly and her flatmate, Bea Nichols, live.[2][3] Gaynor performs a singing and dancing version of the song "(Keep Your) Sunny Side Up" for a crowd of her neighbors, complete with top hat and cane. Later in the film, a dance sequence for the song "Turn on the Heat", including scantily clad and gyrating island women enticing bananas on trees to abruptly grow and stiffen, occurs without Gaynor's participation.[4]
The Times and The New York Times both express the opinion that the film, and the singing voices of Gaynor and Farrell, are all tolerable if not exactly worthy of praise. Despite the sugary sentimentality, the film is engaging, while the cinematography and special effects are impressive.[2][3]
Several times throughout the film Gaynor sings the tune "I'm a Dreamer, Aren't We All?" and, on one occasion, sings it impressively, according to the New York Times.[2] It was written by Buddy DeSylva & Lew Brown (words) and Ray Henderson (music).
An early popular recording was by Paul Whiteman and His Orchestra on October 16, 1929 with a vocal group including Bing Crosby[8] and this reached the charts in 1929.[9] The tune was also recorded by John Coltrane in 1958 [10] and included on his album Bahia (1964).
"Turn on the Heat"
In addition to appearing in the Sunny Side Up, "Turn on the Heat" was recorded as a solo stride piano piece by Fats Waller in 1929, and this recording has been reissued numerous times. The song was also used in the 1933 Pooch the Pup cartoon Hot and Cold.[11]
"(Keep Your) Sunny Side Up"
Another song in the film that would later be used as the theme song to the 1988 British sitcom Clarence.
In the 1950s, the song was used as the theme song for Sunnyside Up, a variety program produced by HSV-7 (a television station in Melbourne, Australia). The song's melody was later adapted by the Essendon Football Club for its club song, "See the Bombers Fly Up", written by Kevin Andrews in 1959.[12]
