Here is a sweet version:

I'd like to build a world a home
And furnish it with love
Grow apple trees and honey bees
And snow white turtle doves
I'd like to teach the world to sing
In perfect harmony
I'd like to hold it in my arms
And keep it company
I'd like to see the world for once
All standing hand in hand
And hear them echo through the hills
For peace throughout the land
That's a song I hear
Sing it along
Let the world sing today
Over and over ...

I nee the lyrics to "I'd Like To Teach The World To Sing".
