No, it's a dirge. And worse, it's NOT a national anthem, it's just a song worshipping someone who by accident of birth and the warmongering, religious bigotry and downright thieving of her ancestors gets to 'rule' us. Oh yes,
and it also is deeply offensive to Scots, describing them as seditious and calling for them to be crushed - I mean, what sort of a national anthem calls for the crushing of over one-fifth of its own population??? If that happened in somewhere like Zimbabwe we'd be demanding sanctions against that country's government!
Let's have All You Need is Love instead.

OK then, it does have some redeeming features - it's not 100% bad.
