As we approach the 21st anniversary of the 9/11 attacks on the United States, and the death today of Queen Elizabeth, I was reminded when the Queen honored the USA by having our National Anthem played at Buckingham Palace. The video quality is poor, but you can see Americans crying, singing, and waving small American flags. It breaks my heart even today.
This is the only time in it’s 200 year history that another country’s national anthem has been played outside Buckingham Palace, apart from during state visits. Her Majesty the Queen personally authorized the Coldstream Guards to break protocol and play this, to give some comfort to Americans stranded in London due to airport closures. It is literally the highest gesture of solidarity Britain could show to another country.

I just updated the video to one of slightly better quality.

Here is another video from that week.
Battle Hymn of the Republic sung by a united congregation of thousands at Saint Paul’s Cathedral for the Memorial Services in London, England. The service was attended by the Royal Family on September 14th 2001 for the 9/11 terrorist attacks on the United States. You can also see Margaret Thatcher in the beginning.
