God save the queen, is it a new song or just simply god save the king?
its just god save the king.
With the word king swapped out for Queen.
As to what happens, someone is supposed to announce the Queen is dead long live the King, there will be a massive burrial with peeps crying everywhere, a huge celebration for the corronation, and the heads on coins will change.
Thats it basically, the question is whether it will be Charles who takes over or if he will stand assice for someone else.
