A couple of edits to tabs elsewhere that should capture the full song.   Play 
around with the hammering that really makes this one nice - listen to the song and 
you'll suss it pretty quickly.  

Intro
A (with hammer) G (x4) Last G chord (1/2 strum pattern) followed by 2 down strum D

Verse 1 
                     A
There's a light on a hill
                      D
That's far out in the distance
                    G
And it calls out my name
                   A
It calls out for a change
                   A
Fare away voices
                    D
That want their own choices
           G
Sigh for a plea
                      A
As it calls out for a change

Chorus
C      D         A
Uuuuuh uuuuuuuuh change
C      D         A
Uuuuuh uuuuuuuuh change
C      D               
Uuuuuh uuuuuuuuh

Verse 2
               A
To the root of mankind
                     D
It bellows out bitter winds
                  G
Youth cry out for today
                      A
Strength to cry for a change
                     A
Yet it seems clear to me
                    D
It pounds inside my soul
                 G
Why don't we all see
                     A
We can cry out for a change

Chorus
C      D         A
Uuuuuh uuuuuuuuh change
C      D         A
Uuuuuh uuuuuuuuh change
C      D               
Uuuuuh uuuuuuuuh

Interlude
A G (played like intro)

A             G
We can change today
A             G
We can change today
A             G       D
We can change today

Verse 3
                A
Deep inside our hearts
                       D
There's a love you can feel
                 G
It's a love that assures
                   A
We can cry out for change
                     A
The dark clouds that did dance
                           D
To the blue skies here before me
                   G
Make it plain to my eyes
                   A
We can cry out for change

Chorus
C      D         A
Uuuuuh uuuuuuuuh change
C      D         A
Uuuuuh uuuuuuuuh change
C      D               
Uuuuuh uuuuuuuuh
