Lyrics:

Once I met a happy little bluebird
I was just as blue as I could be
In a little while I began to smile
When he sang this merry song to me

Just let a smile be your umbrella
On a rainy, rainy day
And if your sweetie cries just tell her
That a smile will always pay

Whenever skies are gray don't worry or fret
A smile will bring us sunshine and you'll never get wet
So let a smile be your umbrella
On a rainy, rainy day

Let a smile be your umbrella
On a rainy, rainy day
And if your sweetie cries just tell her
That a smile will always pay

Whenever skies are gray don't worry or fret
A smile will bring us sunshine and you'll never get wet
So let a smile be your umbrella
Be your big umbrella on a rainy, rainy day
