Mama take this badge off me. I can't use it anymore.. It's gettin' dark too dark to see. Feels like I'm knockin' on heaven's door.. [Chorus]. 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.. [Chorus]. 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
