Someone mentioned the song by Frankie Armstrong, 'song of the second serving maid' from her Tamlin album. It has effective harmonies, fifths sevenths and stuff appropriate to the seriousness of the topic.

He came into the bar I worked one cold Deember night
He was tall and strong and helped break up a fight
I bathed his bleeding face and even bandaged up his hand
And done much more for him than that before the next days light.

In the way of young soldiers in three weeks he was gone
didn't say where to just said it won't be long
Of course i've never seen him since or even heard from him again
And just like the old song says it turned out he'd done me wrong.

....and some more verses..

And what of the soldier I wonder what's become of him.
How many has he killed in the name of King nd kin?
Now he'll be blessed by bishops, maybee medals broach his chest,
And they've the nerve to tell me that they're the ones know best.
That i'm the one to bear all sin ....
etc
To a real climactic ending

whatever you think about abortin, there have been some very powerfull songs written from all sides.
