input: Prior to the group's formation, Sakamoto had been experimenting with electronic music equipment at the Tokyo National University of Fine Arts and Music, which he entered in 1970, including synthesizers such as the Buchla, Moog, and ARP. Hosono, following the break-up of his band Happy End in 1972, became involved in the recording of several early electronic rock records, including Yosui Inoue's folk pop rock album Kori no Sekai (1973) and Osamu Kitajima's progressive psychedelic rock album Benzaiten (1974), both of which utilized synthesizers, electric guitars, electric bass, and in the latter, electronic drums and rhythm machines. Also around the same time, the band's future "fourth member" Hideki Matsutake was the assistant for the internationally successful electronic musician Isao Tomita. Much of the methods and techniques developed by both Tomita and Matsutake during the early 1970s would later be employed by Yellow Magic Orchestra.  Sakamoto first worked with Hosono as a member of his live band in 1976, while Yukihiro Takahashi recruited Sakamoto to produce his debut solo recording in 1977 following the split of the Sadistic Mika Band. Hosono invited both to work on his exotica-flavoured album Paraiso, which included electronic songs produced using various electronic equipment. The band was named "Harry Hosono and the Yellow Magic Band" as a satire of Japan's obsession with black magic at the time, and in late 1977 they began recording Paraiso, which was released in 1978. The three worked together again for the 1978 album Pacific, which included an early version of the song "Cosmic Surfin". Hosono and Sakamoto also worked together alongside Hideki Matsutake in early 1978 for Hosono's experimental "electro-exotica" fusion album Cochin Moon, which fused electronic music with Indian music, including an early "synth raga" song "Hum Ghar Sajan". The same year, Sakamoto released his own solo album, The Thousand Knives of Ryuichi Sakamoto, experimenting with a similar fusion between electronic music and traditional Japanese music in early 1978. Hosono also contributed to one of Sakamoto's songs, "Thousand Knives", in the album. Thousand Knives was also notable for its early use of the microprocessor-based Roland MC-8 Microcomposer music sequencer, with Matsutake as its music programmer for the album.  While Sakamoto was working on Thousand Knives, Hosono began formulating the idea of an instrumental disco band which could have the potential to reach success in non-Japanese-language territories, and invited Tasuo Hayashi of Tin Pan Alley and Hiroshi Sato of Uncle Buck as participants, but they declined. Hosono, Sakamoto and Takahashi eventually collaborated again to form the Yellow Magic Orchestra and they began recording their self-titled album at a Shibaura studio in July 1978. The band was initially conceived as a one-off studio project by Hosono, the other two members being recruited session musicians--the idea was to produce an album fusing orientalist exotica with modern electronics, as a subversion of Orientalism and exoticization.

input: Jefferson was born blind (or possibly partially blind), near Coutchman, Texas. He was the youngest of seven (or possibly eight) children born to Alex and Clarissa Jefferson, who were sharecroppers. Disputes regarding the date of his birth derive from contradictory census records and draft registration records. By 1900, the family was farming southeast of Streetman, Texas, and his birth date is indicated as September 1893 in the 1900 census. The 1910 census, taken in May, before his birthday, further confirms his year of birth as 1893 and indicated that the family was farming northwest of Wortham, near his birthplace.  In his 1917 draft registration, Jefferson gave his birth date as October 26, 1894, further stating that he then lived in Dallas, Texas, and had been blind since birth. In the 1920 census, he is recorded as having returned to Freestone County and was living with his half-brother, Kit Banks, on a farm between Wortham and Streetman.  Jefferson began playing the guitar in his early teens and soon after he began performing at picnics and parties. He became a street musician, playing in East Texas towns in front of barbershops and on street corners. According to his cousin Alec Jefferson, quoted in the notes for Blind Lemon Jefferson, Classic Sides:  They were rough. Men were hustling women and selling bootleg and Lemon was singing for them all night... he'd start singing about eight and go on until four in the morning... mostly it would be just him sitting there and playing and singing all night.  In the early 1910s, Jefferson began traveling frequently to Dallas, where he met and played with the blues musician Lead Belly. Jefferson was one of the earliest and most prominent figures in the blues movement developing in the Deep Ellum section of Dallas. It is likely that he moved to Deep Ellum on a more permanent basis by 1917, where he met Aaron Thibeaux Walker, also known as T-Bone Walker. Jefferson taught Walker the basics of playing blues guitar in exchange for Walker's occasional services as a guide. By the early 1920s, Jefferson was earning enough money for his musical performances to support a wife and, possibly, a child. However, firm evidence of his marriage and children has not been found.

input: On New Year's Day 2011 Wood appeared in a BBC drama Eric and Ernie as Eric Morecambe's mother, Sadie Bartholomew.  For the 2011 Manchester International Festival, Wood wrote and directed That Day We Sang, a musical set in 1969 with flashbacks to 1929. It tells the story of a middle-aged couple who find love after meeting on a TV programme about a choir they both sang in 40 years previously. Although the characters are imaginary, the choir sang with the Halle Orchestra in Manchester's Free Trade Hall on a record that sold more than a million copies. Apart from the pieces on the 1929 recording (Purcell's "Nymphs and Shepherds" and the Evening Benediction from Hansel and Gretel) the score for the musical was written by Wood.  On 22 December 2012 Wood was a guest on BBC Radio Two's Saturday morning Graham Norton Show. On 23 December BBC One screened Loving Miss Hatto, a drama written by Wood about the life of concert pianist Joyce Hatto, the centre of a scandal over the authenticity of her recordings and her role in the hoax. In April 2013, Wood produced a documentary about the history of tea named Victoria Wood's Nice Cup of Tea. In 2013 she played retired constable-turned-security-guard Tracy in BBC Scotland's Case Histories starring Jason Isaacs. She appeared in an episode of QI, broadcast on 13 December 2013, and around the same time made two return appearances on I'm Sorry I Haven't a Clue during the show's 60th series. In March 2014, Wood voiced the TV advertisement for the tour of the old set of Coronation Street. On 5 December 2014 Wood was a guest on BBC's The Graham Norton Show. On 26 December 2014, a television adaptation of That Day We Sang, starring Michael Ball and Imelda Staunton, was shown on BBC Two.  In early 2015, Wood took part in a celebrity version of The Great British Bake Off for Comic Relief and was crowned Star Baker in her episode. She co-starred with Timothy Spall in Sky television's three-part television adaptation of Fungus the Bogeyman, which was first shown on 27, 28 & 29 December 2015, her last acting project and final role.
