I see trees of green, red roses too
Dm7         C       E7         Am     
I see them bloom, for me and you,
      Ab                      G7        C C+ F G7
And I think to myself, What a wonderful world.

I hear babies cry, I watch them grow

And I think to myself what a wonderful world
      Dm7              G7                C
Yes I think to myself, what a wonderful world.
