The jukebox in the cafe when June Haver dances with and sings "I Wish I Could Tell You" to John Payne is a Wurlitzer 412, circa 1936, of which more than 30,000 were produced. The machine held only a dozen 78-rpm records and could only play one side. During WW2, production of jukeboxes was halted as materials were needed for the war effort, and since this film is set in 1943, it stands to reason that a small cafe would still be making good use of its 1936 jukebox. After WW2, jukeboxes went back into full production, and thousands upon thousands were placed in cafes, diners, bars and restaurants nationwide.
Even though this film introduced the song "Give Me the Simple Life" and it plays over and over throughout, another famous song --- made popular in a totally different film --- suddenly appears out of nowhere at exactly 1:18:32. As John Ireland and little Connie Marshall traipse through the jungle looking for the professor's treehouse, "We're Off to See the Wizard" is sung by an off-screen chorus for several minutes. It is truly odd to hear this song made famous in "The Wizard of Oz" so out of context.
