Mama take this badge of me
I can't use it anymore
It's getting dark too dark 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
Feels 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
