This is a great song about social change. The intro seems to be done by hammering on the A chord (eg strum the open strings and then push down the chord quickly into place), and they keep doing this during the song.

There's a light on a ^Ahill That's far out in the ^Ddistance And it calls out my ^Gname It calls out for a ^Achange Far away ^Avoices That want their own ^Dchoices Sigh for a ^Gplea As it calls out for a ^Dchange ^COoh ^DOoh ^AChange ^COoh ^DOoh ^AChange ^COoh ^DOoh ^AWe can change today ^DWe can change today ^GWe can change today ^A

To the root of mankind, It bellows out bitter winds, Youth cry out for today, Strength to cry out for change, Yet it seems clear to me, It pounds inside my soul, Why don't we all see, We can cry out for change. Ooh Ooh Change Ooh Ooh Change Ooh Ooh Deep inside our hearts There's a love You can feel It's a love that assures We can cry out for change The dark clouds that did dance To the blue skies here before me Make it plain to my eyes We can cry out for change Ooh Ooh Change Ooh Ooh Change Ooh Ooh
