Lyrics:

Mama, take this badge away
I can't use it any more
It's getting dark, too dark to see
Feels like I'm knocking on heaven's door

Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door

Mama, put my guns in the ground
I can't shoot them any more
The dark black cloud is coming down
Feels like I'm knocking on heaven's door

Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door
Knock, knock, knocking on heaven's door

Ooh, ooh, ooh, ooh ...

Knock, knock, knocking on heaven's door ...
