This is an excellent World War I song.

The singer is identifed as "Raymond Dixon"--this is really Lambert Murphy

"When You Come Back And You Will Come Back"

Victor 18494

1918

Song by George M. Cohan

From 'Frisco Bay to old Broadway, today all
over the USA, we know we're fighting the foe,
so we all stand steady and ready to go.

We know no fear, we know no tear,
And all we hear is the Yankee cheer.

I heard a girlie say to her boy as he marched away:

When you come back, if you do come back,
You'll hear the Yankee cry, "Ata boy, Jack!"
And when you return remember to bring
Some little thing that you get from the king.

And drop me a line from Germany, do, Yankee Doodle, do.
When you come back, and you will come back,
There's a whole world waiting for you.
