Matt, that is one of the best posts I have read on Xmarks, period!

A note about the London Scottish for those who are not familiar: Lord Elcho, who raised the regiment from Scotsmen living in London, chose "Hodden Grey" on purpose:

This avoided all interclan feeling on the subject of tartan and, as Lord Elcho said "A soldier is a man hunter. As a deer stalker chooses the least visible of colours, so ought a soldier to be clad."

Hodden Grey is a homespun, and also mentioned in the song "The Star o' Rabbie Burns" as the colour of the ploughman's garments.

The Toronto Scottish are an affiliated unit of the London Scottish. Scottish regiments often "twin" with Commonwealth units, ie The Black Watch & the BW of Canada, etc.

Cheers,

Todd
