“Baby Mine” from Dumbo. Music by Frank Churchill, lyrics by Ned Washington, and sung beautifully in the film by Betty Noyes. The song was nominated for Best Original Song at the 1942 Academy Awards and has since become a Disney classic, covered by artists ranging from Brian Wilson and Glenn Miller to Bette Midler. | Disney History Channel

A behind-the-scenes look at Disney’s 1941 production shows how sound effects for Dumbo were created—especially the voice of Casey Jr., the talking train. Using glass scrapers, throat tubes, and early talk-box tech, sound artists brought characters to life with creativity and grit. The footage, taken from The Reluctant Dragon documentary, highlights the ingenious Foley work behind classic cartoons—long before digital sound existed. | History In Pictures
