As for a change in the Anthem, Jerusalem was mentioned, the only problem I see with that is that it is named after a city that is not in the UK. Jerusalem is in Israel. That is like America using an Anthem named “Paris”. It seems odd to me.
‘Jerusalem’ the poem (set to music) isn’t literally about the actual city of Jerusalem, it’s about England.
In fact it’s specifically about Jerusalem not being in England 😄
No it’s not “specifically” about that. It’s about about trying to make England a better place (than a land of “dark satantic mills”). The better place being a conceptual notion of an idyllic and mythic “Jerusalem”. Not about literally sending for the blueprints of the city of Jerusalem from Palestine and ordering a pallet of bricks.
It’s a warning about not being complacent and too nationalistic.
That’s a stretch. Complacency in a sense yes (because it’s about striving to make something imperfect, perfect), warning about being too nationalistic no.
and it’s sung frequently by people who are complacently nationalistic.
The people who sing it do not change it’s content.
