So your time has come, children watch the fools
         ........
Don't let anyone tell you, what you must do......
In the Chorus, the chords are :
          Hear that sound
          There's a voice to be found
          Making changes go round
       Gm(hold)    
          Hear that sound...
After the second chorus, the key changes. The chords in the verse become:
So your time has come, children watch the fools
         ....... 
Don't let anyone tell you, what you must do......
And, in the chorus they become:
          Hear that sound
          There's a voice to be found
          Making changes go round
(finish on)    
          Hear that sound...
