Gallus Moll: but in actual fact the sound system was delivering the (English) national(*offensive) anthem, so I guess he has somehow become royal?
(* the alleged national anthem was originally composed as a rallying song for the citizens of London who were fleeing Bonnie Prince Charlie and his Jacobite army as they approached the city. Not sure how it managed to drop the nasty verse about the Scots then segued into god save the king/queen?!ggggrrrr)

That is not in fact the case. The National Anthem is in fact the anthem of the United Kingdom of Gt Britain and Northern Ireland, not the "English" national anthem, although it's used as such at many sporting events.

The lyrics were written in 1744, not 1745 as you assert, but they were published in the "Gentleman's Magazine" in 1745, and are nothing to do with a rallying cry for citizens of London fleeing Prince Charles' army (which didn't in fact "approach the city"....unless you mean the city of Derby, which is as near as he got).

The "nasty verse about the Scots" was never part of the original lyrics, and didn't appear in either the original publication and performances in 1744, nor in the 1745 lyrics published in the Gentleman's Magazine. It certainly originated in 1745, but so did a great many "alternative" verses, including Jacobite ones such as:

God bless the prince, I pray,
God bless the prince, I pray,
Charlie I mean;
That Scotland we may see
Freed from vile Presbyt'ry,
Both George and his Feckie,
Ever so, Amen

None of these alternative verses, be they anti-Scots, anti-English or anti-French, were ever part of the official anthem, but Scots with a chip on their shoulder (and I do have Scots ancestry myself) always seem to bring this up to "prove" that the anthem is anti-Scotland.

Now I'm neither big on anthems, nor on nationalism, nor have any particular fondness for the royal family....but I do hate historical inaccuracies repeated as "facts" and the "Braveheartisation" of history.
