Smile lyrics

(originally by Nat King Cole)

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 pain and sorrow,
Smile though it may be tomorrow,
You'll see the sun come shining through, for you,
Light up your face with glad ness
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.
Ooh, oh, oooh, mmm, ooh yeah
That's the time you must keep on trying,
Smile what the use of crying?
You'll find that life is still worthwhile,
If you just smile,
Smile though your heart is aching,
Smile even though its breaking,
When there are clouds in the sky,
You'll get by,
That's the time you must keep on trying, (keep on tryin')
Smile, what's the use of crying? (whats the use of crying)
You'll find that life is still worthwhile,
If you just smile,
You'll find that life is still worthwhile,
If you just smile, smile.
