The song Kenneth sings during his audition is to the tune of the chorus from "Shine On, Harvest Moon", a popular early-20th Century standard. The song originated from Tin Pan Ally music publishers during the vaudeville era. Debuting in 1908 for the Ziegfeld Follies, it has been recorded by many artists throughout the century. Two movies of the same name were also made in the 30's and 40's.
