Smile, though your heart is aching ...

Smile, though your heart is aching
Smile, even though its breaking
When there are clouds in the sky, you'll get by
If you smile through your fear and sorrow
Smile and maybe tomorrow
You'll see the sun come shining through for you

Just smile.

(Words by John Turner and Geoffrey Parsons and music by Charlie Chaplin)

Or you can Smile!, the Lily Allen way.
