Mommy told me something
a little girl should know
It's all about the devil
and I've learned to hate him so
She says he causes trouble
when you let him in the room
You never ever leave you
if your heart is filled with gloom
So let the sun shine in,
face it with a grin
Smilers never lose
and frowners never win
So let the sun shine in,
face it with a grin
Open up your heart and
let the sun shine in.
When you are unhappy
the devil wears a grin
But oh, he starts a running
when the light comes pouring in
I know he'll be unhappy cause
I'll never wear a frown
Maybe if we keep on smiling
he'll get tired of hanging around.
