Ma, take the badge off of me
I can't use it any more
It's getting dark, too,dark to see
Feel like I'm knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
（ MUSIC ）
Ma, take these guns away from me
I can't shoot them any more
There's a long black cloud following me
