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 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无限循环
