The London Scottish sing this in memory of being part of the 1st Battalion, 51st Highland Volunteers during the 70s-90s. We sang it again with visiting members of the Liverpool Scottish at our "G" Company dinner last night 26th Feb 10, and used to finish it with the last line "Gerroff me barrow"; this is now "Gerroff me sister".
But I remember hearing another verse along the lines of
"The 51st Division went to France to fight the war,
They looked for days, they looked for nights, but couldnae find the war,
Something something someting..
Says Monty to the 51st get up and get yer guns,
For we're all Scotsmen etc etc

Incidentally, we also sang Billy Connolly's "I am a TA soldier, and the World is scared of me..."
