Lyrics:

Mama, take this badge off of me
I can't use it anymore
It's gettin' 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
I feel like I'm knockin' on heaven's door

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