Bon Jovi - Blood Money

[INTRO]
Db Ab Eb7 Ab

               Db                                           Ab
Hey Patty Garrett, that's what I used to call you.

                         Db                                       Ab
They tell me you want me, but I here they've got you.

                        Db                                          Ab
They made you a law man, with a badge made of silver.

                            Eb7                            Ab
They paid you some money to sell them my blood.

            Ab7                              Db                                 Ab
But you say:   This ain't about me and this ain't about you,

                                    Eb7                              Ab
Or the good and the bad times, we've both been through.

             Ab7                Db                                              Ab
When the lines between brothers and justice have changed,

                                  Eb7                                  Ab
You do what you've got to, 'cause you can't walk away.

                                     Db                                  Ab
I wonder what would have happened if you were the killer

                     Db                                    Ab
And I was the hero, would things be the same?

                        Db                                 Ab
Or would I have traded your life for my own life?

                   Eb7                               Ab
Would I have paid your debts in your place?

            Ab7                                     Db                                 Ab
I don't know.   But this ain't about me and this ain't about you,

                                    Eb7                            Ab7
Or the good and the bad times we've both been through.

             Ab7                Db                                             Ab
When the lines between brothers and justice have changed,

                                  Eb7                                    Ab
You do what you've got to, 'cause you can't walk away.

         Db                            Ab
Blood Money, that's what I call it,

                               Eb7                               Ab7
'Cause money for blood, ain't no fair exchange.

         Db                                    Ab
Blood Money, bought and then sold you,

                                     Eb7                                    Ab
But your conscience is all you can take to your grave.
