In her autobiography, Ethel Merman said that the original lyrics to "Heat Wave": "She started a heat wave by letting her seat wave" was changed for the movie to "She started a heat wave by letting her feet wave"
This was the first time that composer Irving Berlin had worked with Ethel Merman. He told her that he was so impressed with her talent that he would work with her again. He kept that promise and wrote two Broadway shows especially for her: "Annie Get Your Gun" in 1946 and "Call Me Madam" in 1950, the latter of which also starred Merman in the film adaptation: Call Me Madam. Merman also later starred in a film that, like this one, was a cavalcade of Irving Berlin songs, There's No Business Like Show Business.
Three deleted musical numbers survive in pristine condition: "Some Sunny Day" sung by Don Ameche, "In My Harem" sung by Jack Haley, with Wally Vernon and Chick Chandler and "Marching Along With Time" sung by Ethel Merman; all three numbers are included as special features in the DVD release.
