"And did those feet in ancient time" is a poem by William Blake from the preface to his epic Milton: A Poem in Two Books, one of a collection of writings known as the Prophetic Books. The date of 1804 on the title page is probably when the plates were begun, but the poem was printed c. 1808. Today it is best known as the hymn "Jerusalem", with music written by Sir Hubert Parry in 1916. The famous orchestration was written by Sir Edward Elgar. Upon hearing the orchestral version for the first time, King George V said that he preferred "Jerusalem" over the British national anthem "God Save the King". "Jerusalem" is considered to be England's most popular patriotic song; The New York Times said it was "fast becoming an alternative national anthem," and there have even been calls to give it official status
