Lyrics:

Mama take this badge from me
I can't use it anymore
It's getting dark too dark to see
Feel i'm knockin' on heaven's door
Chrous:
Knock knock knockin' on heaven's door (repeat 3x)
Mama wipe this blood from my face
I'm sick and tired of all this war
There's a long hard feelin' and it's hard to chase
Feel i'm knockin' on heaven's door
Chorus
Mama put these guns tot he ground
I can't shoot them anymore
Theres a long black train and it's comin' round
Feels like knockin' on heaven's door
Chorus
