Didn't you just know somebody would bring money into it, demeaning other people's perceptions about the scots... As if it wasn't shame enough being the birthplace of McGonagall, ljc, you want folk to pay for it as well.
On the subject of Bannockburn itself, I remember visiting the display centre there years ago and marvelling at the panoramic painting of the battle, and at the sheer impact of the statue of Bruce on his palfrey. Stirring stuff. But apart from the lyrics posted above, are there many songs about the battle other than just a passing mention such as in "Roses of Price Charlie"... at Bannockburn / Your battle-axe to wield/....? "Flower of Scotland" certainly refers to the Wars of Independence and Bannockburn, but it isn't actually about the battle, being a call to modern scots to have pride in their heritage.
How many songs about the battle are there?
