input question: A friend asked me to answer this question: What is the last name of the person who once said his performance was a fiasco?, using the article: By 1957 Grainger's physical health had markedly declined, as had his powers of concentration. Nevertheless, he continued to visit Britain regularly; in May of that year he made his only television appearance, in a BBC "Concert Hour" programme when he played "Handel in the Strand" on the piano. Back home, after further surgery he recovered sufficiently to undertake a modest winter concerts season. On his 1958 visit to England he met Benjamin Britten, the two having previously maintained a mutually complimentary correspondence. He agreed to visit Britten's Aldeburgh Festival in 1959, but was prevented by illness. Sensing that death was drawing near, he made a new will, bequeathing his skeleton "for preservation and possible display in the Grainger Museum". This wish was not carried out.Through the winter of 195960 Grainger continued to perform his own music, often covering long distances by bus or train; he would not travel by air. On 29 April 1960 he gave his last public concert, at Dartmouth College in Hanover, New Hampshire, although by now his illness was affecting his concentration. On this occasion his morning recital went well, but his conducting in the afternoon was, in his own words, "a fiasco". Subsequently confined to his home, he continued to revise his music and arrange that of others; in August he informed Elsie that he was working on an adaptation of one of Cyril Scott's early songs. His last letters, written from hospital in December 1960 and January 1961, record attempts to work, despite failing eyesight and hallucinations: "I have been trying to write score for several days. But I have not succeeded yet."Grainger died in the White Plains hospital on 20 February 1961, at the age of 78. His body was flown to Adelaide where, on 2 March, he was buried in the Aldridge family vault in the West Terrace Cemetery, alongside Rose's ashes. Ella survived him by 18 years; in 1972, aged 83, she married a young archivist, Stewart Manville. She died at White Plains on 17 July 1979., what would be the answer ????
output answer: Grainger

input question: A friend asked me to answer this question: What person had electrical engineering knowledge?, using the article: Following the Pixies' breakup, Lovering drummed with several artists, including Nitzer Ebb, but turned down an invitation to join the Foo Fighters. Lovering then joined Santiago's band The Martinis, appearing on their song "Free" on the soundtrack of Empire Records. However, he soon left the band to become a touring drummer for Cracker. Lovering moved from band to band, drumming with Tanya Donelly's group on 1997's Lovesongs for Underdogs and with Boston band Eeenie Meenie. After facing difficulty finding new work, Lovering gave up the drums and moved into a rented house that banned drumming.Towards the end of the 1990s, Lovering's friend Grant-Lee Phillips took him to a magic convention. Lovering was very impressed by some of the illusions, and later said "I had to learn how to do it". Mutual friend Carl Grasso invited them to a show at the Magic Castle, a magic-oriented nightclub in Los Angeles. There Lovering met Possum Dixon frontman Rob Zabrecky, and the pair soon became friends. Zabrecky convinced Lovering to apply for a performers' membership to the Magic Castle. After gaining his membership, Lovering reinvented himself as "The Scientific Phenomenalist". His act combined his electrical engineering knowledge with his stage performance experience. His decision to pursue a career in magic was influenced by the fact that as a musician, he "couldn't top the Pixies".As the Scientific Phenomentalist, Lovering performs science and physics experiments in a lab coat while on stage. He shuns traditional magic tricks, and prefers "things that are more mental, using mental powers". He later explained: "It's all kind of upbeat, really weird physics experiments that you'll never see. [...] I'd rather have them [the audience] going 'Is it [magic] or isn't it?' rather than 'It's all science' or 'It's all magic'. So I do kinda weird things that other magicians don't do". Lovering cites sleight-of-hand artist Ricky Jay, mind reader Max Maven and Eugene Burger as influences on his technique. His performances often involve..., what would be the answer ????

input question: A friend asked me to answer this question: What ruler was overthrown by a group whose factional conflicts caused the Second Bulgarian Empire to disintegrate?, using the article: After the conquest of Bulgaria, Basil II prevented revolts by retaining the rule of local nobility and relieving their lands of the obligation to pay taxes in gold, allowing tax in kind instead. The Bulgarian Patriarchate was reduced to an archbishopric, but retained its autocephalous status and its dioceses. Byzantine domestic policies changed after Basil's death and a series of unsuccessful rebellions broke out, the largest being led by Peter Delyan. In 1185 Asen dynasty nobles Ivan Asen I and Peter IV organized a major uprising which resulted in the re-establishment of the Bulgarian state. Ivan Asen and Peter laid the foundations of the Second Bulgarian Empire with Tarnovo as the capital. Kaloyan, the third of the Asen monarchs, extended his dominion to Belgrade and Ohrid. He acknowledged the spiritual supremacy of the pope and received a royal crown from a papal legate. The empire reached its zenith under Ivan Asen II (12181241), when its borders expanded as far as the coast of Albania, Serbia and Epirus, while commerce and culture flourished. Ivan Asen's rule was also marked by a shift away from Rome in religious matters.The Asen dynasty became extinct in 1257. Internal conflicts and incessant Byzantine and Hungarian attacks followed, enabling the Mongols to establish suzerainty over the weakened Bulgarian state. In 1277, swineherd Ivaylo led a great peasant revolt that chased the Mongols out of Bulgaria and briefly made him emperor. He was overthrown in 1280 by the feudal landlords, whose factional conflicts caused the Second Bulgarian Empire to disintegrate into small feudal dominions by the 14th century. These fragmented rump statestwo tsardoms at Vidin and Tarnovo and the Despotate of Dobrudzhabecame easy prey for a new threat arriving from the Southeast: the Ottoman Turks., what would be the answer ????
output answer:
Ivaylo
