How not to toast the Queen!

The string orchestra of the Scots Guards mistakenly began playing the British national anthem before the President had finished his address during a banquet at Buckingham Palace on Tuesday night.

Mr. Obama carried on talking over the start of God Save the Queen and raised his glass to the Queen before the music had finished.

However, the Queen did not appear to be offende3d and thanked the leader for his "very kind" words.
