Lyrics:

Mama, take this badge off of meI can't use it anymore.It's gettin' dark, too dark for me to seeI feel like I'm knockin' on heaven's door.Knock, knock, knockin' on heaven's doorKnock, knock, knockin' on heaven's doorKnock, knock, knockin' on heaven's doorKnock, knock, knockin' on heaven's doorMama, 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 doorKnock, knock, knockin' on heaven's doorKnock, knock, knockin' on heaven's doorKnock, knock, knockin' on heaven's door
