Smile Charles Chaplin (from Modern Times), Nat 'King' Cole (#10 in 1954)

Smile, tho' your heart is aching,
Smile, even tho' 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'll just smile.
