Passage: Although the publicity generated by Five Leaves Left was minor, Boyd was keen to build on what momentum there was. Drake's second album, 1971's Bryter Layter, again produced by Boyd and engineered by John Wood, introduced a more upbeat, jazzier sound.Disappointed by his debut's poor commercial performance, Drake sought to move away from his pastoral sound, and agreed to Boyd's suggestions to include bass and drum tracks. "It was more of a pop sound, I suppose," Boyd later said. "I imagined it as more commercial." Like its predecessor, the album featured musicians from Fairport Convention, as well as contributions from John Cale on two songs: "Northern Sky" and "Fly". Trevor Dann noted that while sections of "Northern Sky" sound more characteristic of Cale, the song was the closest Drake came to a release with chart potential. Cale used heroin during this period, and his older friend Brian Wells suspected that Drake was also using.Boyd and Wood were confident that Bryter Layter would be a success, but it sold fewer than 3,000 copies. Reviews were again mixed: while Record Mirror praised Drake as a "beautiful guitaristclean and with perfect timing, [and] accompanied by soft, beautiful arrangements", Melody Maker described the album as "an awkward mix of folk and cocktail jazz".Soon after its release, Boyd sold Witchseason to Island Records, and moved to Los Angeles to work with Warner Brothers to develop film soundtracks. The loss of his mentor, coupled with the album's poor sales, led Drake into further depression. His attitude to London had changed: he was unhappy living alone, and visibly nervous and uncomfortable performing at a series of concerts in early 1970. In June, Drake gave one of his final live appearances at Ewell Technical College, Surrey. Ralph McTell, who also performed that night, remembered: "Nick was monosyllabic. At that particular gig he was very shy. He did the first set and something awful must have happened. He was doing his song 'Fruit Tree' and walked off halfway through it."In 1971, Drake's family persuaded him to visit a psychiatrist at St Thomas's Hospital, London. He was prescribed antidepressants, but felt uncomfortable and embarrassed about taking them, and tried to hide the fact from his friends. He worried about their side effects and was concerned about how they would react with his regular cannabis use.Island Records urged Drake to promote Bryter Layter through interviews, radio sessions and live appearances. Drake, who by this time was smoking what Kirby described as "unbelievable amounts" of cannabis and exhibiting "the first signs of psychosis", refused. Disappointed by the reaction to Bryter Layter, he turned his thoughts inwards, and withdrew from family and friends. He rarely left his flat, and then only to play an occasional concert or to buy drugs. His sister recalled: "This was a very bad time. He once said to me that everything started to go wrong from [this] time on, and I think that was when things started to go wrong.".
Question: What is the last name of the person who agreed to include bass and drum tracks?

Ex Output:
Northern Sky.

Passage: Dodo Doubleday has been inexplicably reduced from first sergeant to staff sergeant and has resumed being orderly to his regimental commander Colonel Barkley. Sergeant Ames is still a buck sergeant who hates Dodo because he advanced to outrank Ames within Dodo's first 24 hours in the army. Dodo's former comrade in arms Charlie Cobb is also a buck sergeant. As both Cobb and Ames are the best marksman in the regiment but constantly boast of their prowess, Colonel Barkley seeks to find an expert who can outshoot them.
Though possessing a photographic memory that enabled him to advance from private to senior non-commissioned officer in less than 24 hours, Dodo has one weakness: though his book knowledge enables him to give lectures on weapons disassembly and ballistics, he is gun shy and an incompetent marksman. After nearly shooting several of his fellow soldiers on the pistol range, with the actual target being the safest place to hide, Dodo is ordered to go into the woods to practice. There his missed shots impress the picnicking colonel and his daughter Betty when Dodo accidentally shoots a hawk through the eye whilst in flight and after the colonel catches a fish who breaks the line and is in the process of rolling back into the water, an accidental discharge from Dodo's pistol shoots the fish through his eye. Eager to deflate the boasting Ames and Cobb, the colonel bets a month's pay that Dodo can outshoot Ames and Cobb.
Ames and Cobb's hatred of Dodo increases when in the interests of promoting democracy in the United States Army, Betty invites Dodo to dinner at the colonel's quarters, but Ames and Cobb believe they have been invited as well.
Question: Who is picnicking with the man that wants to find someone who can outshoot the buck sergeants?

Ex Output:
Betty.

Passage: During the 1913 Ballets Russes season in Paris, Monteux conducted two more premieres. The first was Jeux, with music by Debussy and choreography by Nijinsky. The choreography was not liked; Monteux thought it "asinine", while Debussy felt that "Nijinsky's cruel and barbarous choreography ... trampled over my poor rhythms like so many weeds". The second new work was Stravinsky's The Rite of Spring given under the French title, Le sacre du printemps. Monteux had been appalled when Stravinsky first played the score at the piano:
I decided then and there that the symphonies of Beethoven and Brahms were the only music for me, not the music of this crazy Russian. ... My one desire was to flee that room and find a quiet corner in which to rest my aching head. Then [Diaghilev] turned to me and with a smile said, "This is a masterpiece, Monteux, which will completely revolutionize music and make you famous, because you are going to conduct it." And, of course, I did.
Despite his initial reaction, Monteux worked with Stravinsky, giving practical advice to help the composer to achieve the orchestral balance and effects he sought. Together they worked on the score from March to May 1913, and to get the orchestra of the Theatre des Champs-Elysees to cope with the unfamiliar and difficult music Monteux held seventeen rehearsals, an unusually large number. Monteux's real attitude to the score is unclear. In his old age he told a biographer, "I did not like Le Sacre then. I have conducted it fifty times since. I do not like it now." However, he told his wife in 1963 that the Rite was "now fifty years old, and I do not think it has aged at all. I had pleasure in conducting the fiftieth anniversary of Le Sacre this spring".
Question: What is the name of the ballet that will completely revolutionize music?

Ex Output:
The Rite of Spring.
