"blaring out 'God Save the Queen'"

God Save The Queen is the national anthem of the United Kingdom and is also the royal anthem of several Commonwealth nations including Australia and Canada.  There are several different versions of the lyrics.  Usually only the first verse is sung, as follows:

God save our gracious Queen

Long live our noble Queen

God save the Queen

Send her victorious

Happy and glorious

Long to reign over us

God save the Queen.
