The colors of the rainbow
So pretty in the sky

Are also on the faces
Of people going by

I see friends shaking hands
Saying, “How do you do?”
They’re really saying
“I love you”

I hear babies cry
I watch them grow

They’ll learn much more
Than I’ll never know

And I think to myself
What a wonderful world
