It certainly needs changing. The current dirge was described by someone I can't remember as a hymn to someone who doesn't exist to someone who shouldn't exist. As we appear to have been recently established as the least religious country on earth (hooray), and there is a healthy minority of English republicans, we have been left with a national anthem that actually alienates the majority of the population if they care to listen to the words. On second thoughts, I think that's so English that maybe we should keep it....
