Problem: "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 an attribution to John Bull is sometimes made. It is the national anthem of the United Kingdom and one of two national anthems used by New Zealand since 1977, as well as for several of the UK's territories that have their own additional local anthem. It is also the royal anthem - played specifically in the presence of the monarch - of all the aforementioned countries, as well as Australia (since 1984), Canada (since 1980), Barbados and Tuvalu.

The phrase "God Save the King" is much older than the song, appearing, for instance, several times in the King James Bible. A text based on the 1st Book of Kings Chapter 1: verses 38-40, "...And all the people rejoic'd, and said: God save the King! Long live the King! May the King live for ever, Amen", has been sung at every coronation since that of King Edgar in 973. Scholes says that as early as 1545 "God Save the King" was a watchword of the Royal Navy, with the response being "Long to reign over us". He also notes that the prayer read in churches on anniversaries of the Gunpowder Plot includes words which might have formed part of the basis for the second verse "Scatter our enemies...assuage their malice and confound their devices". In 1745, The Gentleman's Magazine published "God save our lord the king: A new song set for two voices", describing it "As sung at both Playhouses" (the Theatres Royal at Drury Lane and Covent Garden). Traditionally, the first performance was thought to have been in 1745, when it was sung in support of King George II, after his defeat at the Battle of Prestonpans by the army of Charles Edward Stuart, son of James Francis Edward Stuart, the Jacobite claimant to the British throne. It is sometimes claimed that, ironically, the song was originally sung in support of the Jacobite cause: the word "send" in the line "Send him victorious" could imply that the king was absent. However, the Oxford English Dictionary cites examples of "[God] send (a person) safe, victorious, etc." meaning "God grant that he may be safe, etc.". There are also examples of early eighteenth century Jacobean drinking glasses which are inscribed with a version of the words and were apparently intended for drinking the health of King James II and VII. Scholes acknowledges these possibilities but argues that the same words were probably being used by both Jacobite and Hanoverian supporters and directed at their respective kings. In 1902, the musician William Hayman Cummings, quoting mid-18th century correspondence between Charles Burney and Sir Joseph Banks, proposed that the words were based on a Latin verse composed for King James II at the Chapel Royal.

How is this different than the current song?

Question:
Fred McFeely Rogers (March 20, 1928 - February 27, 2003) was an American television personality, musician, puppeteer, writer, producer, and Presbyterian minister. Rogers was famous for creating, hosting and composing the theme music for the educational preschool television series Mister Rogers' Neighborhood (1968-2001), which featured his kind-hearted grandfatherly personality, and direct connection to his audiences. Originally trained and ordained as a minister, Rogers was displeased with the way television addressed children at the time, and made an effort to change this when he began to write for and perform on local Pittsburgh-area shows dedicated to youth. Rogers developed his own show on WQED in 1968, and it was distributed nationwide by Eastern Educational Television Network.
Rogers was born in Latrobe, Pennsylvania, 40 miles (65 km) southeast of Pittsburgh, to James and Nancy Rogers; he had one sister, Elaine. Early in life, he spent much of his free time with his maternal grandfather, Fred McFeely, who had an interest in music. He would often sing along as his mother would play the piano, and he himself began playing at five. He obtained a pilot's license while still in high school. Rogers graduated from Latrobe High School (1946). He studied at Dartmouth College (1946-48), then transferred to Rollins College in Winter Park, Florida, where he earned a B.A. in Music Composition in 1951. Rogers was also a trained general aviation pilot. At Rollins, he met Sara Joanne Byrd (born c. 1928), an Oakland, Florida, native; they married on June 9, 1952. They had two sons, James (b. 1959) and John (b. 1961). In 1963, Rogers graduated from Pittsburgh Theological Seminary and was ordained a minister in the United Presbyterian Church in the U.S.A. Rogers had an apartment in New York City and a summer home on Nantucket island in Massachusetts. Rogers was red-green color blind, swam every morning, and neither smoked nor drank. He was a vegetarian on ethical grounds, stating "I don't want to eat anything that has a mother." Despite recurring rumors, he never served in the military. His office at WQED Pittsburgh famously did not have a desk, only a sofa and armchairs, because Rogers thought a desk was "too much of a barrier".
