Judy Garland singing “Over The Rainbow” throughout her lifetime. In a letter to composer Harold Arlen, Garland wrote: “As for my feelings toward "Over the Rainbow", it's become part of my life. It is so symbolic of all dreams and wishes that I'm sure that's why people sometimes get tears in their eyes when they hear it.“
The song was almost cut from The Wizard of Oz (1939 ) because MGM chief studio-head Louis B. Mayer and producer Mervyn LeRoy thought it "slowed down the picture.” Thankfully, associate producer Arthur Freed and Garland's vocal coach Roger Edens pleaded to keep it in the film. The song went on to win the Academy Award for Best Original Song and became Garland’s signature song.
