From the album "Spread A Little Happiness".

Lyrics

Even when the darkest clouds are in the sky
You mustn't sigh and you mustn't cry
Spread a little happiness as you go by
Please try
What's the use of worrying and feeling blue
When days are long keep on smiling through
Spread a little happiness till dreams come true
Surely you'll be wise to make the best of every blues day
Don't you realize you'll find next Monday or next Tuesday
Your golden shoes day
Even when the darkest clouds are in the sky
You mustn't sigh and you mustn't cry
Spread a little happiness as you go by
