Mommy told me something
A little girl 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 sunshine in
Face it with a grin
Smilers never lose
And frowners never win

So let the sunshine in
Face it with a grin
Open up your heart
And let the sunshine in

When you are unhappy
The devil wears a grin
But oh, he starts to running
When the lights
Come 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

So let the sunshine in
Face it with a grin
Smilers never lose
And frowners never win

So let the sunshine in
Face it with a grin
Open up your heart
And let the sunshine in

If I forget to say my prayers
The devil jumps with glee
That he feels so awful awful
When he sees
Me on my knees

So if your full of trouble
And You never seem to win
Just open up your heart
And let the sunshine in

So let the sunshine in
Face it with a grin
Smilers never lose
And frowners never win

So let the sunshine in
Face it with a grin
Open up your heart
And let the sunshine in
