Grateful Dead
"Knockin' On Heaven's Door"

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

Mama, put my guns in the ground, I can't shoot them anymoreThat long black cloud is comin' downI feel like I'm knockin' on heaven's door
