I've just voted to keep God Save The Queen

. It's the only clearly Royalist anthem on the list (at the top of the page).
As for that great work - Jerusalem. It can't be the anthem for the whole of the UK because it is specifically English.
I think that there are some people who would like to see Jerusalem used for events such as football matches where England is playing. The only problem is - would the fans remember the words? :shock:
