(点击右边三个点，可调整速度，电脑上可下载)  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
 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
 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
 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
 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
