This "Call out my Mother..." chorus is cribbed from a version of "Boys of the Old Brigade"

Send for the boys of the Girls brigade,
Send out the rank and file,
Send out the Army and the Navy,
They'll face danger with a smile.
Send for the brave Territorials,
They'll keep the Empire free
Send for my Mother,
My sister and my brother
But for Gawd's sake don't send me.

Best Wishes

Walrus
