1939: If Only I Had A Brain by Ray Bolger

Composed by Yip Hapburg (lyrics) and Harold Arlen (music). The song was featured in the 1939 film The Wizard of Oz by the character Scarecrow who was played by actor Ray Bolger. If Only I Had A Brain was originally titled I’m Hanging On To You, having been composed for the 1937 musical Hooray For What! It was dropped from the show and when the composers were asked to write the songs for The Wizard of Oz, Yip Hapburg adapted the song with new lyrics.
