Hey let's do this one rock-and-roll!. Wonderful idea. Let's dance!. Whistle while you work. Put on that grin. And start right in to whistle loud and long. Just hum a merry tune. Just do your best. And take a rest and sing yourself 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. Come on get smart tune up and start. To whistle while you work. And whistle while you work. Come on get smart start to start. To whistle while you work
