Here's the version from What a Singing There Will Be:


Keep On the Firing Line
Traditional

If you're in the struggle for the Lord and right
Keep on the firing line
If you'd win the battle brother, you must fight
So keep on the firing line, my brother
There are many dangers that we all must face
If we die while fighting, it is no disgrace
But cowards in the army should not have a place
So keep on the firing line

Chorus:
You must fight and be brave against all evil
Never run though your foes combine
If you would fight for God and right
Then keep on the firing line

God can never use a soldier he can't trust
Keep on the firing line
If you'd wear the crown, then bear the cross you must
So keep on the firing line, my brother
Life is but to labor for the Master dear
Help to banish darkness and to spread good cheer
Then we shall be rewarded for our service here
If we keep on the firing line

When we get to heaven we will be so glad
Keep on the firing line
We will thank our Father for the call that we had
If we keep on the firing line, my brother
There we'll meet the souls that we helped to win
We led 'em up to heaven from the paths of sin
We'll hear their welcome plaudits and go marching in
If we keep on the firing line


Helen's notes: Great song for joyous bellowing. I learned it first, with minor word changes, as a labor union organizing song.
