Open up your heart and let the sun shine in Mommy told me something A little kid 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 your room He'll 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 So let the sun shine in Face it with a grin Smilers never lose Open up your heart and let the sun shine in 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
