Mummy told me something a little boy should know
Its all about the devil and I've learnt 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 loose 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 and the devil wears a grin
But oh he starts running when the right comes firing in
I know he'll be unhappy ‘cos I never wear a frown
Maybe if I keep smiling he get tired of hanging round
So let the sun shine in, face it with a grin
Smilers never loose 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
If I forget say my prayers the devil jumps with glee
He feels so awful awful when he sees me on my knee
So if your full of troubles 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 loose 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
