Task: Question Answering
Input (English): Passage: Various reports appeared to confirm that the symphony's release was imminent. The Finnish composer Leevi Madetoja mentioned in 1934 that the work was virtually complete; an article by the Swedish journalist Kurt Nordfors indicated that two movements were complete and the rest sketched out. As pressure to produce the symphony increased, Sibelius became increasingly withdrawn and unwilling to discuss his progress. In December 1935, during an interview in connection with his 70th birthday celebrations, he indicated that he had discarded a whole year's work; this pointed to a full-scale revision of the Eighth. However, when The Times's correspondent asked for details of the work's progress Sibelius became irritated. He was furious when Downes continued to pester him for information, on one occasion shouting "Ich kann nicht!" ("I cannot!").A receipt found among Sibelius's papers refers to a "Symphonie" being bound by the firm of Weilin & Göös in August 1938. While it is not established that this transaction related to the Eighth, the Sibelius scholar Kari Kilpeläinen points out that none of the earlier symphony scores carry the unnumbered heading "Symphonie", and asks: "Could he have omitted the number to prevent news of the now completed Eighth from spreading? Or did he not give the work a number at all, because he was not satisfied with it?" The composer's daughter Katarina spoke of the self-doubt that afflicted her father at this time, aggravated by the continuing expectations and fuss that surrounded the Eighth Symphony. "He wanted it to be better than the other symphonies. Finally it became a burden, even though so much of it had already been written down. In the end I don't know whether he would have accepted what he had written."Sibelius remained in Finland during the Winter War of 1939–40, despite offers of asylum in the United States. After the war ended in March 1940 he moved with his family to an apartment on Kammiokatu (later renamed Sibeliuksenkatu or 'Sibelius Street' in his honour) in the Töölö district of Helsinki, where they remained for a year. During that time they were visited by the pianist Martti Paavola, who was able to examine the contents of Sibelius's safe. Paavola later reported to his pupil Einar Englund that among the music kept there was a symphony, "most likely the Eighth".
