Lyrics:

Mama, take this badge off of me
I can't use it anymore.
It's gettin' dark, too dark for me to see
I feel like I'm knockin' on heaven's door.
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Mama, put my guns in the ground
I can't shoot them anymore.
That long black cloud is comin' down
I feel like I'm knockin' on heaven's door.
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
