girl in the war...laurel begging hardy for a gun

I can't get this song out of my head.

And what's worse I can't figure out what it means. Even to me.

Peter said to Paul
"All those words that we wrote
Are just the rules of the game and the rules are the first to go"
But now talkin' to God is Laurel beggin' Hardy for a gun
I gotta girl in the war, man I wonder what it is we done

Paul said to Petey
"You gotta rock yourself a little harder;
Pretend the dove from above is a dragon and your feet are on fire"
And I got a girl in the war, Paul the only thing I know to do
Is turn up the music and pray that she makes it through

Because the keys to the kingdom got locked inside the kingdom
And the angels fly around in there, but we can't see them
And I gotta girl in the war, Paul I know that they can hear me yell
If they can't find a way to help, they can go to Hell
If they can't find a way to help her, they can go to Hell

Paul to Petey "you gotta rock yourself a little harder;
Pretend the dove from above is a dragon and your feet are on fire"
But I gotta girl in the war, Paul her eyes are like champagne
They sparkle, bubble over, in the morning all you got is rain
Sparkle, bubble over, in the morning all you got is rain
They sparkle, bubble over, in the morning all you got is rain
