With a Smile and a Song - Snow White and the Seven Dwarfs

Walt Disney's 1937 film: Snow White and the Seven Dwarfs.

Lyrics:

With a smile and a song
Life is just a bright sunny day
Your cares fade away
And your heart is young

With a smile and a song
All the world seems to waken anew
Rejoicing with you
As the song is sung

There's no use in grumbling
When the raindrops come tumbling
Remember, you're the one
Who can fill the world with sunshine

When you smile and you sing
Everything is in tune and it's spring

And life flows along
With a smile and a song
