Smile though your heart is aching
Smile even though it's breaking
When there are clouds in the sky (With Finn: you'll get by)

Rachel and Finn:
If you smile through your pain and sorrow
Smile and maybe tomorrow
You'll see the sun come shining through for you

Mercedes (New Directions):
Light up your face with gladness (Gladness...)
Hide every trace of sadness
Although a tear (Tear...)

Mercedes with New Directions:
may be ever so near

Mercedes and Artie (New Directions):
That's the time (That's the time) you must keep on trying
(Smile) Smile, what's the use of crying?
You'll find that life is still worthwhile (with New Directions: If you just smile)

Artie:
Oooooo

Mercedes:

Mercedes and Artie (New Directions):
That's the time (That's the time) you must keep on trying (Rachel: Ooooh)

You'll find that life is still worthwhile (with New Directions: If you just smile)

Smile even though it's breaking (Mercedes: It's breaking)
