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
