Lyrics:

The grass will be greener, the sky more blue
That's what the feeling does to you
When you're happy, happy, happy
Happy, happy, happy, happy in love
Whoa

Friends will notice you're acting more gay
All your troubles will be washed away
When you're happy, happy, happy
Happy, happy, happy, happy in love

You won't care if the sun don't shine
All your worries will be left behind
You'll be happy, happy, happy, happy all the time
When you're happy, happy, happy in love
Sha la la

You'll have a smile upon your face
All your worries will be washed away
When you're happy, happy, happy
Happy, happy, happy, happy in love

Sha la la la la la, sha la la la la la la
Sha la la la la la la, sha la la la la la
Sha la la la la la la, sha la la la la la
Sha la la la la la la da

You won't care if the sun don't shine
All your worries will be left behind
You'll be happy, happy, happy, happy all the time
When you're happy, happy, happy in love
Sha la la

You'll wear a smile upon your face
The world will seem like a better place
When you're happy, happy, happy
Happy, happy, happy, happy in love

Sha la la la la la, sha la la la la la la
Sha la la la la la la, sha la la la la la
Sha la la la la la la, sha la la la la la
Sha la la la la la la da
(Happy, happy in love)

When you're happy, happy, happy
Happy, happy, happy, happy in love
(Happy, happy in love)

When you're happy, happy, happy
Happy, happy, happy, happy in love
(Happy, happy in love)
