I agree with Jack , but the digression has thrown up one interesting aspect that is relevant to the original post: 'good' or 'popular' songs don't come out of the side that won - yes, I know this is a huge generalisation, but bear with me a moment. Plenty of 'jingoism' (a word that came out of an Anglo-Russian war song in the first place) DURING conflict, but the sentimental popular song comes out of losing. This applies even centuries later - which is the area Dad Perkins is looking at - e.g. Trelawny: written early 20th Century, but referring to the Cornish Bishop centuries earlier - the song became an anthem to Cornishmen although Cornwall has only been officially recognised as a County ever since. It is only in recent years with an upsurgance of songwriting, another reinvention of celticism, and a genuine local pride that new positive songs are passing into popular currency and even some them still have a historic back reference. Another example of the style of faux-nostalgia time-shift between the original cause and the new song, of course, is Flower of Scotland!

Fascinating subject!
