Question: What year did the Beatles release a song which mentions performer and circus proprietor Pablo Fanque?
Context: Friedrich Wilhelm August Pagel aka William Pagel (5 February 1878 Plathe, Pomerania, Germany - 13 October 1948 Knysna) was a ‘strong man’ and South African circus proprietor.  He was the second of eight children raised by Antonia Fraudnich and August Pagel. William Batty (1801–1868) was an equestrian performer, circus proprietor, and longtime operator of Astley's Amphitheatre in London.  Batty was one of the most successful circus proprietors in Victorian England and helped launch the careers of a number of leading Victorian circus personalities, such as Pablo Fanque, the versatile performer and later circus proprietor (best known today from his mention in The Beatles song "Being for the Benefit of Mr. Kite! "), and W.F. Wallett, one of the most celebrated clowns of the era.  Also, while in operation for only two years, Batty's most lasting legacy is probably Batty's Grand National Hippodrome, also known as Batty's Hippodrome, an open-air amphitheate he erected in 1851 in Kensington Gardens, London, to attract audiences from the Crystal Palace Exhibition nearby. John Sanger (1816 – 22 August 1889) was an English circus proprietor. William George "Billy" Smart Sr. (25 April 1894–25 September 1966) was a British showman, fairground proprietor and circus proprietor, the founder and owner of Billy Smart's Circus. 'Lord' George Sanger (23 December 1825 – 28 November 1911) was an English showman and circus proprietor.  Born to a showman father, he grew up working in travelling peep shows.  He successfully ran shows and circuses throughout much of the nineteenth century with his brother John.  He retired in 1905 and was murdered by a disgruntled employee in 1911. Stafford Bullen (20 March 1925, Bathurst, New South Wales - November 2001, Sydney) was a circus proprietor and co-founder of the African Lion Safari, Warragamba. Pablo Fanque (born William Darby 30 March 1810 in Norwich, England; died 4 May 1871 in Stockport, England) was an English equestrian performer and circus proprietor, the first non-white British circus owner in Britain.  His circus was the most popular in Victorian Britain for 30 years, a period that is regarded as the golden age of the circus. William Frederick "W.F." Wallett (November 1806 in Hull, England – 13 March 1892 at Beeston, Nottinghamshire, England) was a popular circus clown in Victorian England, who also enjoyed modest celebrity in the United States.  After he performed before Queen Victoria in 1844 at Windsor Castle, Wallett began promoting himself as "the Queen's Jester," and described himself this way in the title of his 1870 autobiography.  For many years, he performed in the circus owned by his good friend Pablo Fanque (whose name is familiar to many today from his mention in The Beatles song, "Being for the Benefit of Mr. Kite! ") Wallett also helped manage Fanque's circus. Henry Ringling North (November 12, 1909 – October 2, 1993) was American businessman, as a circus proprietor who was the vice president, treasurer, director and operations chief, while his brother, John Ringling North, was the president and chairman of the Ringling Bros. and Barnum & Bailey Circus, founded by their uncles. "Being for the Benefit of Mr. Kite!"  is a song by the English rock band the Beatles, from their 1967 album "Sgt. Pepper's Lonely Hearts Club Band."  It was primarily written and composed by John Lennon, with additional input claimed by Paul McCartney.  The song is credited to Lennon–McCartney.
