Question: Who is sometimes considered the author of the official national anthem of Bermuda?

full_context: Document 1: E Ola Ke Alii Ke Akua: "E Ola Ke Aliʻ i Ke Akua", translated as "God Save the King", was one of Hawaii's four national anthems. It was composed in 1860 by Prince William Charles Lunalilo, who later became King Lunalilo. Prior to 1860, the Kingdom of Hawaii lacked its own national anthem and had used the British royal anthem "God Save The King". A contest was sponsored in 1860 by Kamehameha IV, who wanted a song with Hawaiian lyrics set to the tune of the British anthem. The winning entry was written by the 25-year-old Lunalilo and was reputed to have been written in 20 minutes. Lunalilo was awarded 10 dollars, which later donated to the Queen's Hospital. His composition became Hawaii's first national anthem. It remained Hawaii's national anthem until 1866, when it was replaced by Queen Liliʻ uokalani's composition "He Mele Lahui Hawaii".
Document 2: Kongesangen: Kongesangen ("King's Song") is Norway's royal anthem. The lyrics come in several versions. The first version ("Gud signe kongen vor") was written by Henrik Wergeland, but the version used today and quoted below was written by Gustav Jensen for the coronation of Haakon VII and Maud of Wales in 1906. It was inspired by the British royal and national anthem, and set to the tune of "God Save the Queen".
Document 3: God Bless Our Homeland Ghana: "God Bless Our Homeland Ghana" is the national anthem of Ghana. The anthem "God Bless Our Homeland Ghana" was originally written and composed by Philip Gbeho and adopted in 1957.
Document 4: Long live our noble Duke: "Long live our noble Duke" is an alteration traditionally made within the historic county boundaries of Lancashire to the anthem 'God Save the Queen'. The anthem still uses the same lyrics and instrumental tune, but the second line "Long live our noble Queen" is changed to "Long live our noble Duke" out of respect to the reigning monarch in their capacity as the Duke of Lancaster. The title is always held by the monarch as head of the royal Duchy of Lancaster, historically Lancaster being the county town of Lancashire. No matter if the sovereign is male or female, they always retain the style of Duke, therefore the variant second line never changes even if 'God save the Queen' changes to 'God Save the King' and vice versa.
Document 5: Monarchy of the United Kingdom: The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the constitutional monarchy of the United Kingdom, its dependencies and its overseas territories. The current monarch and head of state, Queen Elizabeth II, ascended the throne on the death of her father, King George VI, on 6 February 1952.
Document 6: Thomas Arne: Thomas Augustine Arne ( ; 12 March 1710, London – 5 March 1778, London) was an English composer, best known for the patriotic song "Rule Britannia". He also wrote a version of "God Save the King", which became the British national anthem, and the song "A-Hunting We Will Go". Arne was the leading British theatre composer of the 18th century, working at Drury Lane and Covent Garden.
Document 7: Hail to Bermuda: "Hail to Bermuda" is the national song of Bermuda, written by Bette Johns. The official anthem is the national anthem of the United Kingdom, "God Save the Queen", as the island is a British overseas territory.
Document 8: List of national anthems: Most nation-states have anthems, defined as "a song, as of praise, devotion, or patriotism"; most anthems are either marches or hymns in style. A hymn can become a national anthem by a provision in the state's constitution, by a law enacted by its legislature, or simply by tradition. A royal anthem is a patriotic song similar to a national anthem, but it specifically praises or prays for a monarch or royal dynasty. Such anthems are usually performed at public appearances by the monarch or during other events of royal importance. Some states use the royal anthem as the national anthem, such as the anthem of Jordan.
Document 9: Come Ye Blessed: "Come Ye Blessed" is the territorial song of the Pitcairn Islands. "God Save the Queen" is the territory's official national anthem. "Come Ye Blessed" is also the official territorial song of Norfolk Island and it is sung at most island events.
Document 10: God Save the Queen: "God Save the Queen" (alternatively "God Save the King", depending on the gender of the reigning monarch) is the national or royal anthem in a number of Commonwealth realms, their territories, and the British Crown Dependencies. The author of the tune is unknown and it may originate in plainchant, but a 1619 attribution to John Bull is sometimes made.
Document 11: Heil dir, Hannover: Heil dir, Hannover (English: Hail to thee, Hanover), was the national anthem of the Electorate, and later Kingdom of Hanover, adopted in the early 18th century. Like other many rulers in the 17th & 18th century, George I of Hanover and Great Britain instructed George Handel to create an anthem. Handel's melody remained the United Kingdom of Great Britain and Ireland's anthem after the end of the personal union in 1837. Also many other German states made this melody their anthem. For example, it was used in the Grand Duchy of Oldenburg and the Kingdoms of Bavaria and Prussia. After 1871, it became the anthem of the German Empire with the lyrics "Heil dir im Siegerkranz". The last Holy Roman Emperor and German king, Francis II, was very impressed by Handel's theme an instructed his Court musician Haydn to create the "Kaiserhymne", which became his imperial anthem and continued to be used in the new Austrian Empire after he dissolved the Holy Roman Empire.
Document 12: List of historical national anthems: The oldest national anthem, defined as "a song, as of praise, devotion, or patriotism", is the Dutch national anthem "Het Wilhelmus", which was written between 1568 and 1572, but not then given any official status. The first anthem to be officially proclaimed as such was "God Save The Queen", adopted by Great Britain in 1745. "Het Wilhelmus" was declared the national anthem of the Netherlands in 1932; both of these anthems remain in use today. A royal or imperial anthem is a song that is similar in patriotic character to a national anthem, but which specifically praises a monarch, or royal dynasty. Some states have doubled their royal or imperial anthem as their national anthem.
Document 13: Commonwealth realm: A Commonwealth realm is a sovereign state that is a member of the Commonwealth of Nations and shares the same person, currently Elizabeth II, as its head of state and reigning constitutional monarch, but retains a crown legally distinct from the other realms.

Document 15: To Anacreon in Heaven: "The Anacreontic Song", also known by its incipit "To Anacreon in Heaven", was the official song of the Anacreontic Society, an 18th-century gentlemen's club of amateur musicians in London. Composed by John Stafford Smith, the tune was later used by several writers as a setting for their patriotic lyrics. These included two songs by Francis Scott Key, most famously his poem "Defence of Fort McHenry". The combination of Key's poem and Smith's composition became known as "The Star-Spangled Banner", which was adopted as the national anthem of the United States of America in 1931.
