My mother told me something that everyone should know
It's all about the devil and I 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

[ guitar ]

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 'cos I'll never wear a frown
Maybe if we keep on smiling he'll get tired of hanging round

So let the sunshine in...
[ steel ]

If I forget to say my prayers the devil jumps with glee
But oh! he feels so awful when he sees me on my knee
So if you're full of trouble and you never seem to win
Just open up your heart and let the sunshine in

So let the sunshine in...
