G        D                    Am
  Mama, take this badge from me
G         D          C
  I can't use it anymore
G                   D              C
  It's getting dark  too dark to see
G                  D                   C
  Feels like I'm knockin' on heaven's door

I can't shoot them anymore
That cold black cloud is coming down
Feels like I'm knockin' on heaven's door
