Dave's Wife mentioned this song earlier in this thread.

This is mostly my own transcription, but I found the Latin words online. I also listened to David Olney's recording on his album "Women across the River" (2002); it helped me fill in a few muffled words on the Ronstadt/Harris recording.

1917
Written by David Olney
As sung by Linda Ronstadt & Emmylou Harris on "Western Wall: The Tucson Sessions" (1999)

The strange young man who comes to me,
A soldier on a three-day spree,
Who needs one night's cheap ecstasy
    And a woman's arms to hide him.
He greets me with a courtly bow,
And hides his pain by acting proud,
And he drinks too much and he laughs too loud.
    But how can I deny him?
Let us dance beneath the moon.
I'll sing to you Clair de Lune.
The morning always comes too soon.
    But tonight the war is over.

He speaks to me in schoolboy French
Of a soldier's life inside a trench,
And the look of death and the ghastly stench.
    I do my best to please him.
He puts two roses in a vase,
Two roses sadly out of place
Like the gallant smile on his haggard face.
    Playfully I tease him.
Hold me 'neath the Paris sky.
Let's not talk of how or why.
Tomorrow's soon enough to die,
    But tonight the war is over.

We make love too hard, too fast.
He falls asleep, his face a mask.
Then he wakes with the shakes and he drinks from his flask.
    I put my arms around him.
Oh, they die in the trenches and they die in the air.
In Belgium and France, the dead are everywhere,
And they die so fast there's no time to prepare
    A decent grave to surround them.

Old world glory, old world fame,
The old world's gone, gone up in flames,
And nothing will ever be the same,
    And nothing lasts forever.
Oh, I'd pray for him, but I've forgotten how,
And there's nothing, nothing that can save him now,
But there's always another with the same funny bow,
    And who am I to deny them?

Lux aeterna luceat eis, Domine,
Cum sanctis tuis in aeternum, quia pius eis.
Requiem aeternum dona eis, Domine.
    Tonight the war is over.
Quia pius eis,
Lux aeterna luceat eis, Domine,
Cum sanctis tuis in aeternum, quia pius eis,
Requiem aeternum dona eis, Domine.
    Tonight the war is over.
