A  D  E

A                      Gm
Old pirates, yes, they rob I;
     D                 Cm
Sold I to the merchant ships,
A                 Gm
Minutes after they took I
D                  Cm
From the bottomless pit.

A              Gm
But my hand was made strong
D                Cm
By the hand of the almighty.
A                 Gm
We forward in this generation
D           E
Triumphantly.

E                A
Wont you help to sing
D     E        A
These songs of freedom? -
      D     E         Gm
cause all I ever have:
D   E      A
Redemption songs;
D   E     A
Redemption songs.
