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 bloom." So let the sunshine in, face it with a grin Smilers never lose and frowners never wins So let the sunshine in, patient with a grin Open up your heart and let the sunshine in. When you are unhappy the devil wears a grin But aw, he starts to running when the rain 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. So let the sunshine in, face it with a grin Smilers never lose and frowners never wins So let the sunshine in, patient with a grin Open up your heart and let the sunshine in. If I forget to say my prayers the devil jumps with plea But all he feels so 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 sunshine in. So let the sunshine in, face it with a grin Smilers never lose and frowners never wins So let the sunshine in, patient with a grin Open up your heart and let the sunshine in
