This is what England’s national anthem should be after the legitimate line is restored. It will have changes to emphasize that the monarch not only reigns but rules, and rules over parliament. It will still be called God save the King/Queen depending on the monarch’s gender
God save our gracious King/Queen!
Long live our noble King/Queen!
God save the King/Queen!
Send him/her victorious,
Happy and glorious,
Long to rule over us,
God save the King/Queen.
O Lord our God arise,
Scatter his/her enemies
And make them fall;
Have their leaders captured,
Hung drawn and quartered,
On Thee our hopes we fix,
God save us all!
Thy choicest gifts in store,
On him/her be pleased to pour;
Long may he/she rule:
May he/she defend our laws,
And ever give us cause,
To sing with heart and voice,
God save the King/Queen!
