Q: Passage: Lennon met Cynthia Powell (1939–2015) in 1957, when they were fellow students at the Liverpool College of Art. Although Powell was intimidated by Lennon's attitude and appearance, she heard that he was obsessed with the French actress Brigitte Bardot, so she dyed her hair blonde. Lennon asked her out, but when she said that she was engaged, he screamed out, "I didn't ask you to fuckin' marry me, did I?" She often accompanied him to Quarrymen gigs and travelled to Hamburg with McCartney's girlfriend to visit him. Lennon was jealous by nature and eventually grew possessive, often terrifying Powell with his anger and physical violence. Lennon later said that until he met Ono, he had never questioned his chauvinistic attitude toward women. He said that the Beatles song "Getting Better" told his own story, "I used to be cruel to my woman, and physically – any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace."Recalling his July 1962 reaction when he learned that Cynthia was pregnant, Lennon said, "There's only one thing for it Cyn. We'll have to get married." The couple wed on 23 August at the Mount Pleasant Register Office in Liverpool, with Brian Epstein serving as best man. His marriage began just as Beatlemania was taking off across the UK. He performed on the evening of his wedding day and would continue to do so almost daily from then on. Epstein feared that fans would be alienated by the idea of a married Beatle, and he asked the Lennons to keep their marriage secret. Julian was born on 8 April 1963; Lennon was on tour at the time and did not see his infant son until three days later.Cynthia attributed the start of the marriage breakdown to Lennon's use of LSD, and she felt that he slowly lost interest in her as a result of his use of the drug. When the group travelled by train to Bangor, Wales in 1967 for the Maharishi Yogi's Transcendental Meditation seminar, a policeman did not recognise her and stopped her from boarding. She later recalled how the incident seemed to symbolise the end of their marriage. After Cynthia arrived home at Kenwood, she found Lennon with Ono and left the house to stay with friends. Alexis Mardas later claimed to have slept with her that night, and a few weeks later he informed her that Lennon was seeking a divorce and custody of Julian on the grounds of her adultery with him. After negotiations, Lennon capitulated and agreed to let her divorce him on the same grounds. The case was settled out of court in November 1968, with Lennon giving her £100,000 ($240,000 in US dollars at the time), a small annual payment and custody of Julian. 
Question: What is the first name of the child of the person that began to use LSD and lose interest in his wife?

A: Julian.

Q: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?

A: Ferrier.

Q: Passage: Visual elements employed during Nine Inch Nails concerts have often included numerous lighting, stage and projection effects employed to accompany and augment presentation.  Prior to the Fragility tour in 2000, Reznor reflected that "I’ve adopted a philosophy of the way to present Nine Inch Nails live that incorporates a theatrical element. I want it to be drama. I want my rock stars to be larger than life, you know? The Kurt Cobains of the world, I’m sick of that shit. I don’t want a gas station attendant being my hero. I grew up with Gene Simmons. I grew up with Ziggy Stardust."Many songs are typically accompanied with specially designed visual aids, including synchronized lighting effects and projected stock-footage montages.  Early performances of the song "Hurt", for example, were accompanied by a projected montage of clouds, charred bodies, mushroom clouds, maggots, and war refugees, a performance of which is featured in the song's music video.  Recent performances of the song, however, have featured less lighting effects.
Since 1999, the visual presentation of Nine Inch Nails live shows have been directed by Rob Sheridan, while Bill Viola designed a large triptych display for the Fragility tour.  The images displayed on the triptych focused on storm and water imagery.  And All That Could Have Been features an audio commentary track by Viola describing the display and his inspirations for it.For the Live: With Teeth tour, Roy Bennett and Martin Phillips were responsible for the lighting design and stage design respectively.  Bennett explained in a 2005 interview that much of the lighting was done using a series of LED lights arranged in "stalactites or stalagmites [formations] to tie in to the album artwork".  DLP projectors were also used to project images onto a gauze screen in front of the stage.
Using the gauze projection-screen, Phillips, Reznor, and Sheridan devised a "gag" where they projected "a sheet of glass shattering onto a downstage kabuki scrim that would drop as the glass shatters fell. ... We settled on Trent swinging his guitar at the gauze [and] shattering it, but with all the pieces falling up as the [screen] flew out".  This technique can be seen in the tour documentary Beside You in Time.  In contrast to the lighting of previous tours, Performance 2007 featured minimal lighting that was designed to shadow Reznor and the band.The visual elements of the live shows has been subject to much commentary.  The Boston Globe described the Fragility tour as "one of the most outstanding light shows in memory".  A reviewer from the Contra Costa Times described a Live: With Teeth performance as being "heightened by just the right amount of dark purple or blue spotlights, with up-lighting from the stage front, giving the band a horror-flick feel". 
Question: What is the last name of the lighting designer that explained how the lighting for the Live: With Teeth tour was done in a 2005 interview?

A:
Bennett.
