The song was sung in the show by The Dolly Sisters. Judy Garland sang it in the 1941 film Ziegfeld Girl. It was subsequently sung by Jack Oakie in the 1944 film The Merry Monahans and was again featured in the 1945 film The Dolly Sisters (1945 in film), where it was sung by John Payne. It was also included for part of the run (and in the cast album) of the 1973 revival of Irene.
At the end of the rainbow there's happiness And to find it how often I've tried But my life is a race, just a wild goose chase And my dreams have all been denied!
Why have I always been a failure? What can the reason be? I wonder if the world's to blame? I wonder if it could be me?
I'm always chasing rainbows Watching clouds drifting by! My schemes are just like all my dreams Ending in the sky!
Some fellows look and find the sunshine I always look and find the rain! Some fellows make a winning sometime I never even make a gain! Believe me . . .
I'm always chasing rainbows Waiting to find a little blue bird in vain!
