I'd like to teach the world to sing The New Seekers (#7 in 1971), The Hillside Singers (#13 in 1972)

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

    That's the song I hear, let the world sing today
    A song of peace that echos on and never goes away

 
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.
  Chorus
 
I'd like to see the world for once
All standin' hand in hand
And hear them echo through the hills
For peace throughout the land.
  Chorus
