"Smile" lyrics

Smile though your heart is aching smile even though it's 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

Light up your face with gladness hide every trace of sadness
Although a tear may be ever so near
That's the time you must keep on trying smile what's the use of crying
You'll find that life is still worthwhile if you just smile
...
