Just 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, then take a rest
and sing yourself a song
when there's not too much to do
don't let it bother you
forget your troubles,
try to be like the cheerful chickadee
and whistle while you work
come on, get smart, tune up and start
to whistle while you work
