You could be right, Glueman, although it's been quite well documented – actually, it was Danish soldiers during the first world war. Unfortunately, my grandfather died many years ago so I can't ask him if he had personal experience of this, although I have it in my mind that he was. The Old English and Old Norse roots are very similar.

I was always told that is was the wind blowing from the urinals! (And Driffield is supposed to be the coldest place in England).
