Lyrics:

When you're smilin'
The whole world smiles with you
An' when you're laughin'
An' really laughin'
The sun comes shinin' through...

But, when you're cryin',
You bring on the rain,
So, stop you're sighin',
Be happy again!

Oh! Keep on smilin'
'Cause when you're smilin'
The whole world smiles with you...
