Wild Bill Davison - When You're Smiling lyrics

I saw a blind man, He was a kind man, Helping a fellow along, One could not see, One could not walk, But they both were humming this song; When you're smiling, When you're smiling, The whole world smiles with you, When you're laughing, When you're laughing, The sun comes shining through, But when you're crying you bring on the rain,
