Knocking on heavens door

Mama, take this badge off of meI 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 groundI can't shoot them anymore.
That long black cloud is comin' downI 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
