很吵很燥， 但是今天很想唱，

Mama take this badge from me
I can't use it anymore
It's getting dark too dark to see
Feels 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, eh yeah
Mama put my guns in the ground
I can't shoot them anymore
That cold black cloud is comin' down
Feels 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
