(edit: Coca Cola used this song in their adverts back in the 70s)

I'd like to build the 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 through out the land

(That's the song I hear)
