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 fears and sorrows 
Smile and there'll be a tomorrow 
You'll see the [bad word] 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 even trying, 
Smile, what's the use of crying, 
You'll find the life is still worth while if you just smile
