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 and take a rest
and sing your self a song.
When there's too much to do
Don't let it bother you, forget your troubles,
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.
