Example Input: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North. 
Question: What is the first name of the person who unwell and unhappy during his brief tenure?
Example Output: Charles.

Example Input: Passage: Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007.
Perry rose to fame in 2008 with the release of her second album, a pop rock record titled One of the Boys, and its singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its sapphic themes. Her third album, Teenage Dream (2010), ventured into disco, and was her first album to top the U.S. Billboard 200. It topped the U.S. Billboard Hot 100 with the singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)", while "The One That Got Away" reached number three on the chart. The album became the first by a female artist to produce five number-one songs in the U.S., and the second overall after Michael Jackson's album Bad. In March 2012, she re-issued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake". Her fourth album, Prism (2013), was her second to peak atop the U.S. charts. It is influenced by pop and dance, and she became the first artist with multiple videos to reach one billion views on Vevo with the videos for its songs "Roar" and "Dark Horse". Her fifth album, Witness (2017), delved into electropop and became her third album to reach number one in the U.S. "Chained to the Rhythm" was the album's most successful single, breaking Spotify's record at the time for most first-day streams for a song by a female artist.
Perry has received various awards, including four Guinness World Records, five American Music Awards, a Brit Award, and a Juno Award, and has been included in the annual Forbes lists of highest-earning women in music from 2011–2018. Her estimated net worth as of 2016 is $125 million. She is one of the best-selling music artists of all time, having sold more than 100 million records globally throughout her career. In film, she released an autobiographical documentary titled Katy Perry: Part of Me in 2012, and voiced Smurfette in the 2011 film The Smurfs and its sequel in 2013. Perry also began serving as a judge on American Idol in 2018. 
Question: What is the better-known last name of the person who signed a recording contract with Capitol Records in April 2007?
Example Output: Perry.

Example Input: Passage: Drake began recording his debut album Five Leaves Left later in 1968, with Boyd as producer. Drake skipped lectures to travel by train to the sessions in Sound Techniques studio, London. Inspired by John Simon's production of Leonard Cohen's album Songs of Leonard Cohen, Boyd was keen that Drake's voice would be recorded in a similar close and intimate style, "with no shiny pop reverb". He sought to include a string arrangement similar to Simon's, "without overwhelming ... or sounding cheesy". To provide backing, Boyd enlisted various contacts from the London folk rock scene, including Fairport Convention guitarist Richard Thompson and Pentangle bassist Danny Thompson (no relation). To provide string arrangements, Boyd already had in mind Richard A. Hewson.
Initial recordings did not go well: the sessions were irregular and rushed, taking place during studio downtime borrowed from Fairport Convention's production of their Unhalfbricking album. Tension arose as to the direction of the album: Boyd was an advocate of George Martin's approach of "using the studio as an instrument", while Drake preferred a more organic sound. Dann has observed that Drake appears "tight and anxious" on bootleg recordings from the sessions, and notes a number of Boyd's unsuccessful attempts at instrumentation. Both were unhappy with Hewson's contribution, which they felt was too mainstream for Drake's songs. Drake suggested his college friend Robert Kirby as a replacement. Though Boyd was sceptical about taking on an inexperienced amateur music student, he was impressed by Drake's uncharacteristic assertiveness, and agreed to a trial. Kirby had previously presented Drake with some arrangements for his songs. While Kirby provided most arrangements for the album, its centrepiece "River Man", which echoed the tone of Delius, was orchestrated by the veteran composer Harry Robertson.
Post-production difficulties delayed the release by several months, and the album was poorly marketed and supported. In July, Melody Maker described Five Leaves Left as "poetic" and "interesting", though NME wrote in October that there was "not nearly enough variety to make it entertaining". It received little radio play outside shows by more progressive BBC DJs such as John Peel and Bob Harris. Drake was unhappy with the inlay sleeve, which printed songs in the wrong running order and reproduced verses omitted from the recorded versions. In an interview, his sister Gabrielle said: "He was very secretive. I knew he was making an album but I didn't know what stage of completion it was at until he walked into my room and said, 'There you are.' He threw it onto the bed and walked out!". 
Question: What is the full name of the person who provided most arrangements for the album?
Example Output:
Robert Kirby.
