Whistle While You Work - Bunny Berigan
Just, whistle while you work (whistle)
Put on that grin and start right in,
To whistle loud and long.
Just hum a merry tune (hum)
Just do your best,
Then take a rest and sing yourself a song.
When there's too much to do,
Don't let it bother you,
Forget your trouble, try to be just like a cheerful chick-a-dee,
And whistle while you work (whistle)
Come on get smart
Tune up and start
To whistle while you work.
