This is how it is on the sheet music from home. I've transposed it out of Ab as it seems easier in G

    G    B7 Em   G7          C    D9    G
  I wish I knew how it would feel to be free; 
    C    G                     D      A       D
  I wish I could break all the chains holding me.     
    G    B7      Em   G7      C          D9       G
  I wish I could say all the things that I should say          
   C#dim   G    B7      Em    C#dim    G          D9sus4   G
  Say 'em loud, say 'em clear for the whole round world to hear.
