In centuries past ... if the English had known that the "word of power" was free, Scotland would simply be known as a few of the Northern counties of England.

King Eddy I would be like "Oy, Willy Wallace, I'll give ye three wagons full of beer if ye and yer we friends 'll accept me rule."
Willy "Ye mus be daft ... FREEDOM!!!"
Eddy "But I'll give them to ya fer ... free"
Willy "FREE D'em wagons, we be English now!"

And they all would live happily ever after ... At least until Brexit

Enjoy the Barley wine!!
