"Forget your troubles come on get happy!"
So interesting -- someone who struggled with their own personal peace mind would be such a magnetic conduit for this message. "Get Happy" was written by Harold Arlen (who also wrote Somewhere Over the Rainbow) and Ted Koehler.
Sung here by Ms. Garland in her last musical for MGM - Summer Stock...
The art of the performer to use their instrument to deliver a message they may or may not be able to take in, never ceases to astound me.
Here she is again interwoven with Happy Days Are Here Again and Streisand by her side.
