According to The Judy Room, “this is the only filmed record of how Judy sang ‘Over The Rainbow’ throughout the 1940s.”
Classic FM named it one of the most poignant of wartime songs:
Composed by Harold Arlen for the movie The Wizard of Oz (1939), ‘Somewhere Over the Rainbow’ gained a new poignancy during the war. Judy Garland performed it live for American troops in 1943, and a special recording with the Tommy Dorsey Orchestra was released and sent to soldiers, as a promise of better days to come.
And of course, there’s the performance that started this blog: Ella Fitzgerald scatting in 1969.
