I didn’t remember all the lyrics to this song but it seem appropriate:
“Just whistle while you work
And cheerfully together we can tidy up the place
So hum a merry tune
It won't take long when there's a song to help you set the pace
And as you sweep the room
Imagine that the broom
Is someone that you love and soon you'll find you're dancing to the tune
When hearts are high the time will fly so whistle while you work”
