Mommy told me something
A little kid should know
It's all about the devil
And I've learned to hate him so
She said he causes trouble
When you let him in the room
He will 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 to 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 'round
If I forget to say my prayers
The devil jumps with glee
But he feels so awful awful
When he sees me on my knees
So if you're full of trouble
And you never seem to win
Just open up your heart and let the sun shine in
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
