Hanging on the Old Barbed Wire! 
"Hanging on the Old Barbed Wire" (Roud 9618) is a war song of World War I.  (The song is also known as: "Has anyone seen the Colonel?")

This song is also the official song of Princess Patricia's Canadian Light Infantry. 

The song sarcastically recounts the location of various army members, not to be found in the combat zone, and concludes by describing the location of the old battalion: "hanging on the old barbed wire". A barbed wire fence separated the front-line trench from No Man's Land, and men brave or unfortunate enough to go over the top of the dug-out were often quickly shot and their bodies caught in the barbed wire. 

This troop song was not popular with officers, who thought it bad for morale, though attempts to suppress it were unsuccessful.
Original Lyrics

There are several different versions of this song, though all share the final two lines. One version: 

If you want to find the Sergeant,
I know where he is, I know where he is, I know where he is.
If you want to find the Sergeant, I know where he is,
He's lying on the canteen floor.
I've seen him, I've seen him, lying on the canteen floor,
I've seen him, I've seen him, lying on the canteen floor.
If you want to find the Quarter-bloke
I know where he is, I know where he is, I know where he is.
If you want to find the Quarter-bloke, I know where he is,
He's miles and miles behind the line.
I've seen him, I've seen him, miles and miles and miles behind the line.
I've seen him, I've seen him, miles and miles and miles behind the line.
If you want the Sergeant-major,
I know where he is, I know where he is, I know where he is.
If you want the Sergeant-major, I know where he is.
He's tossing off the privates' rum.
I've seen him, I've seen him, tossing off the privates' rum.
I've seen him, I've seen him, tossing off the privates' rum.
If you want to find the C.O.,
I know where he is, I know where he is, I know where he is.
If you want the C.O., I know where he is
He is down in a deep dug-out,
I've seen him, I've seen him, down in a deep dug-out,
I've seen him, I've seen him, down in a deep dug-out.
If you want the old battalion,
I know where they are, I know where they are, I know where they are
If you want to find the old battalion, I know where they are,
They're hanging on the old barbed wire,
I've seen 'em, I've seen 'em, hanging on the old barbed wire.
I've seen 'em, I've seen 'em, hanging on the old barbed wire.
A variant last line is "if you want to find the privates". 
Another variation 4th verse sees C.O replaced with colonel, put at the start and,"He's On another 7 days leave"
