We know the key to unity all people
It's in the dream that you had so long ago
That lives in all of the hearts of the people
That believe in unity
We'll make the dream become a reality
I know we will
Because our hearts tell us so



(I'm not quite sure with the chords of the chorus,
wheter it is just one chord.
You might add an F at the end.
You might play it totally different: C and am alternating.
Try it out. :)
