Now once it was told to me, we're born with a magic key
It opens the door to miracles of spring
It takes you to wishing wells, to ice cream and carousels
And yet this magic key won't unlock a thing

Unless you have a happy, you have a happy
Have a happy, warm smiling face
I start believin', in believin'
Let your address be sunshine place
[ Lyrics from: http://www.lyricsfreak.com/e/elvis+presley/have+a+happy_20049227.html ]
There's love and there's joy I'm told
Much more than your heart can hold
It's there like the ring you'd grab on a merry-go-round
The world isn't half as gray with friends on a rainy day
But people keep away when you wear a frown, you've got

To have a happy, you have a happy
Have a happy warm smiling face
Start believin', in believin'
Let your address be sunshine place
Let your address be sunshine place
Let your address be sunshine place
