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
So stop your sighing be happy again
Keep on smiling 'cause when you're smiling
The whole world smiles with you
I used to worry
I used to hurry
Each time it started to rain
Now I see light
Learned wrong from right
And you'll never hear me complain;
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
So stop your sighing be happy again
Keep on smiling 'cause when you're smiling
