input: Juan Ponce de Leon was born in the village of Santervas de Campos in the northern part of what is now the Spanish province of Valladolid. Although early historians placed his birth in 1460, and this date has been used traditionally, more recent evidence shows he was likely born in 1474. The surname Ponce de Leon dates from the 13th century. The Ponce de Leon lineage began with Ponce Velaz de Cabrera, descendant of count Bermudo Nunez, and Sancha Ponce de Cabrera, daughter of Ponce Giraldo de Cabrera. Before October 1235, a son of Ponce Vela de Cabrera and his wife Teresa Rodriguez Giron named Pedro Ponce de Cabrera married Aldonza Alfonso, an illegitimate daughter of King Alfonso IX of Leon. The descendants of this marriage added the "de Leon" to their patronymic and were known henceforth as the Ponce de Leon.  The identity of his parents is still unknown, but he appears to have been a member of a distinguished and influential noble family. His relatives included Rodrigo Ponce de Leon, Marquis of Cadiz, a celebrated figure in the Moorish wars.  Ponce de Leon was related to another notable family, the Nunez de Guzmans, and as a young man he served as squire to Pedro Nunez de Guzman, Knight Commander of the Order of Calatrava. A contemporary chronicler, Gonzalo Fernandez de Oviedo y Valdes, states that Ponce de Leon gained his experience as a soldier fighting in the Spanish campaigns that defeated the Moors in Granada and completed the re-conquest of Spain in 1492.

input: Lead Belly was born Huddie William Ledbetter on the Jeter Plantation near Mooringsport, Louisiana, on January 20, 1888 or 1889 (generally accepted to be the former). The 1900 United States Census lists "Hudy Ledbetter" as 12 years old, born January 1888, and the 1910 and 1930 censuses also give his age as corresponding to a birth in 1888. The 1940 census lists his age as 51, with information supplied by wife Martha. However, in April 1942, when Ledbetter filled out his World War II draft registration, he gave his birth date as January 23, 1889, and his birthplace as Freeport, Louisiana ("Shreveport"). His grave marker bears the date given on his draft registration.  Ledbetter was the younger of two children born to Wesley Ledbetter and Sallie Brown. The pronunciation of his name is purported to be "HYEW-dee" or "HUGH-dee." He can be heard pronouncing his name as "HUH-dee" on the track "Boll Weevil," from the Smithsonian Folkways album Lead Belly Sings for Children. His parents had cohabited for several years, but they legally married on February 26, 1888. When Huddie was five years old, the family settled in Bowie County, Texas.  The 1910 census of Harrison County, Texas, shows "Hudy" Ledbetter living next door to his parents with his first wife, Aletha "Lethe" Henderson. Aletha is registered as age 19 and married one year. Others say she was 15 when they married in 1908. It was in Texas that Ledbetter received his first instrument, an accordion, from his uncle Terrell. By his early twenties, having fathered at least two children, Ledbetter left home to make his living as a guitarist and occasional laborer. When Lead Belly was released from his last prison sentence, the United States was deep in the Great Depression, and jobs were very scarce. In September 1934, in need of regular work in order to avoid cancellation of his release from prison, Lead Belly asked John Lomax to take him on as a driver. For three months, he assisted the 67-year-old in his folk song collecting around the South (Alan Lomax was ill and did not accompany his father on this trip).

input: From 1967, the show had become closely associated with the BBC radio station Radio 1, usually being presented by DJs from the station, and between 1988 and 1991 the programme was simulcast on the radio station in FM stereo. However, during the last few years of the 1980s the association became less close, and was severed completely (although not permanently) in a radical shake-up known as the 'Year Zero' revamp.  Following a fall in viewing figures and a general perception that the show had become 'uncool' (acts like The Clash had refused to appear in the show in previous years), a radical new format was introduced by incoming executive producer Stanley Appel (who had worked on the programme since 1966 as cameraman, production assistant, director and stand-in producer) in October 1991, in which the Radio 1 DJs were replaced by a team of relative unknowns, such as Claudia Simon and Tony Dortie who had previously worked for Children's BBC, 17-year-old local radio DJ Mark Franklin, Steve Anderson, Adrian Rose and Elayne Smith, who was replaced by Femi Oke in 1992. A brand new theme tune ('Now Get Out Of That'), title sequence and logo were introduced, and the entire programme moved from BBC Television Centre in London to BBC Elstree Centre in Borehamwood.  The new presenting team would take turns hosting (initially usually in pairs but sometimes solo), and would often introduce acts in an out-of-vision voiceover over the song's instrumental introduction. They would sometimes even conduct short informal interviews with the performers, and initially the Top 10 countdown was run without any voiceover. Rules relating to performance were also altered meaning acts had to sing live as opposed to the backing tracks for instruments and mimed vocals for which the show was known. To incorporate the shift of dominance towards American artists, more use was made of out-of-studio performances, with acts in America able to transmit their song to the Top of the Pops audience "via satellite". These changes were widely unpopular and much of the presenting team were axed within a year, leaving the show hosted solely by Dortie and Franklin (apart from the Christmas Day editions, when both presenters appeared) from October 1992, on a week-by-week rotation.
