OUR SERGEANT MAJOR
Written by George Formby, Harry Gifford & Fred E. Cliffe
Performed by George Formby in "George Takes the Air" (1938) and "Somewhere in England" (1940)

Now there's a sergeant major, enjoys life while he can.
He proves to all the ladies he's a soldier and a man.

He sticks out his chest, two pillows in his vest,
A bolster under his rotunda, our sergeant major.
His medals break our hearts. He won them playing darts.
And while competing, who was cheating? Our sergeant major.
    He's far away the worst friend we've ever had.
    When he's far away, well, we're mighty glad.
In the canteen bar, you know what sergeants are.
When we've passed out, who's the last out? Our sergeant major.

He's got a raucous voice. His language isn't choice.
In clink we'd shove him. How we love him! Our sergeant major.
His weight about he'll throw, the wicked so-and-so.
Who'd even smother his own mother? Our sergeant major.
    He's far away the worst friend we've ever had.
    When he's far away, well, we're mighty glad.
Our bugler goes his rounds, and when the bugle sounds,
Forever lasting, who's he blasting? Our sergeant major.
***
Now, he makes raw recruits just tremble in their boots.
He calls 'em slackers. Who's gone crackers? Our sergeant major.
His feet fill up the road, knock-kneed and pigeon-toed.
We'd sooner shoot him than salute him, our sergeant major.
    He's far away the worst friend we've ever had.
    When he's far away, well, we're mighty glad.
The mascot goat we own, so big and fat has grown.
Wild and warlike, he's far more like our sergeant major.
