Input: Consider Input: Passage: After further work as a répétiteur at the opera in Budapest, and with his standing enhanced by his association with Toscanini, Solti was given his first chance to conduct, on 11 March 1938. The opera was The Marriage of Figaro. During that evening, news came of the German invasion of Austria. Many Hungarians feared that Hitler would next invade Hungary; he did not do so, but Horthy, to strengthen his partnership with the Nazis, instituted anti-semitic laws, mirroring the Nuremberg Laws, restricting Hungary's Jews from engaging in professions. Solti's family urged him to move away. He went first to London, where he made his Covent Garden debut, conducting the London Philharmonic for a Russian ballet season. The reviewer in The Times was not impressed with Solti's efforts, finding them "too violent, for he lashed at the orchestra and flogged the music so that he endangered the delicate, evocative atmosphere." At about this time Solti dropped the name "György" in favour of "Georg".After his appearances in London Solti went to Switzerland to seek out Toscanini, who was conducting in Lucerne. Solti hoped that Toscanini would help find him a post in the US. He was unable to do so, but Solti found work and security in Switzerland as vocal coach to the tenor Max Hirzel, who was learning the role of Tristan in Wagner's opera. Throughout the Second World War, Solti remained in Switzerland. He did not see his father again: Mor Stern died of diabetes in a Budapest hospital in 1943. Solti was reunited with his mother and sister after the war. In Switzerland he could not obtain a work permit as a conductor, but earned his living as a piano teacher. After he won the 1942 Geneva International Piano Competition he was permitted to give piano recitals, but was still not allowed to conduct. During his exile, he met Hedwig (Hedi) Oeschli, daughter of a lecturer at Zürich University. They married in 1946. In his memoirs he wrote of her, "She was very elegant and sophisticated. ... Hedi gave me a little grace and taught me good manners – although she never completely succeeded in this. She also helped me enormously in my career". 
Question: What disease killed the father of the man who debuted with Covent Garden in London?

Output: diabetes.


Input: Consider Input: Passage: Yorke said that the starting point for the record was the "incredibly dense and terrifying sound" of Bitches Brew, the 1970 avant-garde jazz fusion album by Miles Davis. He described the sound of Bitches Brew to Q: "It was building something up and watching it fall apart, that's the beauty of it. It was at the core of what we were trying to do with OK Computer." Yorke identified "I'll Wear It Proudly" by Elvis Costello, "Fall on Me" by R.E.M., "Dress" by PJ Harvey and "A Day in the Life" by the Beatles as particularly influential on his songwriting. Radiohead drew further inspiration from the recording style of film soundtrack composer Ennio Morricone and the krautrock band Can, musicians Yorke described as "abusing the recording process". Jonny Greenwood described OK Computer as a product of being "in love with all these brilliant records ... trying to recreate them, and missing."According to Yorke, Radiohead hoped to achieve an "atmosphere that's perhaps a bit shocking when you first hear it, but only as shocking as the atmosphere on the Beach Boys' Pet Sounds." They expanded their instrumentation to include electric piano, Mellotron, cello and other strings, glockenspiel and electronic effects. Jonny Greenwood summarised the exploratory approach as "when we've got what we suspect to be an amazing song, but nobody knows what they're gonna play on it." Spin characterised OK Computer as sounding like "a DIY electronica album made with guitars".Critics suggested a stylistic debt to 1970s progressive rock, an influence that Radiohead have disavowed. According to Andy Greene in Rolling Stone, Radiohead "were collectively hostile to seventies progressive rock ... but that didn't stop them from reinventing prog from scratch on OK Computer, particularly on the six-and-a-half-minute 'Paranoid Android'." Writing in 2017, The New Yorker's Kelefa Sanneh said OK Computer "was profoundly prog: grand and dystopian, with a lead single that was more than six minutes long.". 
Question: What is the name of the person who described the sound of Bitches Brew as "building something up and watching it fall apart"?

Output: Yorke.


Input: Consider Input: Passage: Nick Rivers, an American rock star, travels to East Germany (which is represented as like Hitler's regime) to perform at a cultural festival, which secretly serves the East German government as a diversion for a military operation with the intent of reuniting Germany under their rule. At a dinner, Nick encounters Hillary Flammond, a member of the local resistance movement, attempting to avoid the authorities. He pretends to be her date to get to know her, and performs an impromptu song and dance, mistakenly thinking he was asked to do so, to the delight of Hillary and the diners but to the annoyance of General Streck, the mastermind of the "reunification" plot.
Nick later sees Hillary at a ballet, where she expects to rendezvous with the resistance leader but she is met by the police instead. Nick saves her and they try to escape, but Nick turns himself in so that Hillary can get away. He is taken to a prison where he is questioned and tortured, but he knows nothing and does not break. In an escape attempt, he ends up in the secret prison lab of Dr. Paul Flammond, a brilliant scientist developing the "Polaris naval mine", a device that can destroy the entire NATO submarine fleet as part of the government's plot. The Germans force him to work by threatening to kill his daughter Hillary. Nick is recaptured and scheduled for execution. 
Question: What is the full name of the person who performs a song and dance?


Output: Nick Rivers.
