In the british national anthem...

Yes, unless Charles becomes a professional drag artist. Then it remains the same.

Yes. The instant the Queen died. Royal Tradition. She doesn't even get the chance to get cold.

The Queen is Dead
Long Live the King

what if the british monarch indentifies as an attack helicopter ?

It’s an awful dirge in my option , but it is now , ‘ ‘ God save the King ‘
Hurrah !

The day that Elizabeth died, a few women gathered outside Buckingham palace and sang God Save the King. It was very poignant -- sang very gently and sweetly, it both expressed mourning over the loss of the Queen and well-wishes for the new King.

The original lyrics had the word King, and the song was written for a specific King who was facing danger in battle at the time.

I do think "Rule Britannia" would be awesome as our anthem,but it is what it what is.

Yes in fact it was originally written as King before being changed 70 years ago so now it changes back.
But I don’t expect it to be sung with nearly as much fervor as it had been the last 70 years

It’s originally god save the king I think 🤓

Yes.
Still a dirge.

I thought it was save lol

Yes it does

Yes - it is now "God save the king". Other references to gender specific pronouns are also changed accordingly.

Yes was changed for Elizabeth and now has changed back for Charles

Yes we now sing God save our gracious King.

It is now God save the King

yes- it's now God save the King

It was God save our Queen and after she died and Charles was made king it became God save our king 👑

Possibly

Yes, that’s my understanding.

No it changes from king to queen, not the other way around.
