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
