1.) Mama take this badge from me
I cant use it any more.
It sgetting dark to dark to see
feels like I m knocking on heavens door.

Ref.:
knock knock knocking on heavens door
knock knock knocking on heavens door
knock knock knocking on heavens door
knock knock knocking on heavens door

2.) Mama put my guns in the groundI cant shoot them any more
That dark black gloud i comming down,
feels like I m knocking on heavens door

Ref.:knock knock knocking on heavens door
knock knock knocking on heavens door
knock knock knocking on heavens door
knock knock knocking on heavens door
