wnw, I have no disagreement with a British National Anthem as such. I was born in Northumberland (north of the "actual" border built by the Romans) so could never be English despite the success of politicians in moving the border. Additionally, with my name and obvious Scottish ancestry on my father's side I am more inclined towards Scotland. Despite this, I accept that my Nationality is British and not something else. Consequently I do believe that a "real" British Anthem would be something to be proud of. For the last wee whilies all countries of the British Isles have fought side by side. For example, who could ever forget the bravery of those soldiers at Rourke's Drift? They were mainly Welsh by surname despite the fact that it was an English regiment.
We will always have "Men of Harlech", "Flower of Scotland" numerous Irish songs and the occasional English one - "Land of Hope and Glory" probably being the best, but there are times when we need to be British. We are tiny insiginificant countries on our own. Proud and fierce yes, but small in the modern world. I remember when Scotland could take on the world at Rugby with a team from Melrose, Hawick and Galashiels. Wales did not need much more than the Pontypool front row in those days - maybe Gareth, Dai and JPR to back them up. I was born in a mining village called Ashington which has produced almost a full English (regrettably) soccer team including Jackie Milburn and his relatives the Charlton brothers of 1966 fame. Yet this is not enough.
I am bedblocker age now, so it is probably easier, but I would happily go out under the Union Flag with a British Anthem. I know Peter Wells is musically inclined, perhaps this is his opportunity. And no "political correctness" towards non Brits!!!!!
