This is my first submit, I liked one of the other chords on here, but I changed 
the G chord for an Em, as the song sounds wrong with such a happy chord in it...
So it's just standard tuning:
Capo on the 2nd fret

Chords used:

Am:       x02210
Fmaj7:    x03210
C:        x32010
Em:       022000

 Intro:    Am    Fmaj7    C    Em   x2


                 Am
 You've got the words to change a nation
           Fmaj7
 but you're biting your tongue
                 C
 You've spent a life time stuck in silence
          Em
 afraid you'll say something wrong
    Am                         Fmaj7
 If no one ever hears it how we gonna learn your song?
     C
 So come on, come on 
  Em
 Come on, come on 

               Am
 You've got a heart as loud as lions 
       Fmaj7
 So why let your voice be tamed?
       C
 Baby we're a little different
             Em
 there's no need to be ashamed
                 Am
 You've got the light to fight the shadows
        Fmaj7

  C                Em
 Come on, Come on
