Land of Hope and Glory is still British though, we need something English. Sadly Jerusalem is probably all we've got, although I did hear someone once mention "There'll Always Be An England". Just need one hashed verse:England's anthem at tournaments should be Land of Hope and Glory. (Mind you it is all Hope but never Glory for our football team).
God Save the Queen should only be played when representing all the UK.
There'll always be an England
While there's a country lane,
Wherever there's a cottage small
Beside a field of grain.
There'll always be an England,
And England shall be free,
If England means as much to you
As England means to me!
