"God Save the Queen", or "God Save the King", is an anthem used in a number of Commonwealth realms. It is the national anthem of the United Kingdom, Norfolk Island, one of the two national anthems of the Cayman Islands and New Zealand (since 1977) and the royal anthem of Canada (since 1980), Australia (since 1984), the Isle of Man, Belize, Jamaica, and Tuvalu. In countries not previously part of the British Empire the tune of "God Save the Queen" has also been used as the basis for different patriotic songs, though still generally connected with royal ceremony. The authorship of the song is unknown, and beyond its first verse, which is consistent, it has many historic and extant versions: Since its first publication, different verses have been added and taken away and, even today, different publications include various selections of verses in various orders. In general only one, or sometimes two verses are sung, but on rare occasions three.
In Britain, the Queen (or King) is saluted with the entire anthem, while other members of the royal family who are entitled to royal salute (such as the Prince of Wales) receive just the first six bars. The first six bars also form part of the Vice Regal Salute in Commonwealth realms outside the United Kingdom (e.g., in Canada, the governors general and lieutenant are saluted with the first six bars of "God Save the Queen", followed by the first four and last four bars of "O Canada"). The words of the song, like its title, are adapted to the gender of monarch, with "King" replacing "Queen", "he" replacing "she", and so forth, when a king reigns. In the United Kingdom, the last line of the third verse is also changed.
