I'd like to buy 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
(sing with me)
in perfect harmony
(perfect harmony)
I'd like to buy the world a Coke
and keep it company
That's the real thing
I'd like to teach the world to sing
in perfect harmony
I'd like to buy the world a Coke
and keep it company
It's the real thing
Coke is what the world wants today
Coca-Cola is the real thing
Coke is what the world wants today
Coca-Cola is the real thing
