Question

who wrote national anthem of london

Answer 1

The origins of “God Save the Queen” are lost in obscurity, but there is no doubt whatever that the words and the tune, as we know them today, suddenly became widely popular in September, 1745. In that month, demonstrations of loyalty to the reigning house were in special demand. Prince, Charles Edward, the Young Pretender, had routed Cope at Prestonpans, and was about to invade England; London was preparing to defend itself and its Hanoverian rulers. An example of popular feeling was given on September 28th when the entire male caste of Drury Lane theatre announced their intention of forming a special unit of the Volunteer Defence Force. That evening they gave a performance of Jonson’s The Alchemist. At its conclusion there was an additional item. Three of the leading singers of the day—Mrs. Cibber, Beard and Reinhold —stepped forward and began a special anthem:

“God bless our Noble King,

God Save great George our King ...”.
Thus we cannot say who actually wrote the song...
