As the unofficial anthem (or rather, one of them) has it, "those days are gone now, and in the past they must remain".
I'm English-born, a Woollyback from the Wirral. I lived most of my first 60 years in England and only came here to Glasgow in retirement, but I feel right at home here. What strikes you first of all, after just a few weeks here, is how very different it is in feel, subtleties of everyday life, and even differences in law that can possibly catch you out (though you aren't likely to get into deep trouble) which make you feel that this is distinctly a different country in the way that Wales isn't.
More alarming is to realise, when you watch or read the London-based media, that there's very little about Scotland in 'national' news and general interest content. It's only when you've been here a while that the implications sink in of London newwsreaders saying "The north" when they mean Manchester, which is three hours on the train ~south~ of here - Glasgow is in the south of Scotland too, there's an awful lot of north to go to from here.
It's hard not to sympathise when Scots feel like they are a quaint afterthough, all tartan, shortbread and pipes and not a modern country the size of Denmark or New Zealand and just as capable of making its own way in the world as they do. After all, in the course of human history it's not that long since Scotland was a proud, independent nation. How many English people know that at Agincourt Scotland was on the other side? Nobody ever taught me that. Vive la vielle alliance! Alba gu brath!
So that's why, to return to that song, many Scottish people are feeling "that we can still rise now, to be the nation again that stood against him".
