Passage: "Imagine" is a song co-written and performed by English musician John Lennon. The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace without the barriers of borders or the divisions of religion and nationality and to consider the possibility that the whole of humanity would live unattached to material possessions. Shortly before his death, Lennon said that much of the song's "lyric and content" came from his wife Yoko Ono, and in 2017, she received a co-writing credit.Lennon and Ono co-produced the song and album of the same name with Phil Spector. Recording began at Lennon's home studio at Tittenhurst Park, England, in May 1971, with final overdubs taking place at the Record Plant, in New York City, during July. One month after the September release of the LP, Lennon released "Imagine" as a single in the United States; the song peaked at number three on the Billboard Hot 100 and the LP reached number one on the UK chart in November, later becoming the most commercially successful and critically acclaimed album of Lennon's solo career. Although not originally released as a single in the United Kingdom, it was released in 1975 to promote Shaved Fish, a compilation LP and it reached number six on the chart that year. The photograph on the cover was taken by May Pang in 1974. The song has since sold more than 1.6 million copies in the UK; it reached number one following Lennon's murder in December 1980. In 1985, the Central Park Conservancy memorialised a portion of the park in honour of Lennon, called Strawberry Fields, with a mosaic that reads "Imagine".BMI named "Imagine" one of the 100 most-performed songs of the 20th century. The song ranked number 30 on the Recording Industry Association of America's list of the 365 Songs of the Century bearing the most historical significance. It earned a Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. A UK survey conducted by the Guinness World Records British Hit Singles Book named it the second best single of all time, while Rolling Stone ranked it number three in their list of "The 500 Greatest Songs of All Time". Since 2005, event organisers have played it just before the New Year's Times Square Ball drops in New York City. Dozens of artists have performed or recorded versions of "Imagine", including Madonna, Stevie Wonder, Joan Baez, Lady Gaga, Elton John and Diana Ross. Emeli Sandé recorded a cover for the BBC to use during the end credits montage at the close of the 2012 Summer Olympics coverage in August 2012. "Imagine" subsequently re-entered the UK Top 40, reaching number 18.

Passage: Three years after the events of the previous film, ex-CIA operative Frank Moses tries to lead a normal life with girlfriend Sarah Ross. He dismisses Marvin Boggs' claims that enemies are still after them; Marvin drives off and his car explodes. Although Frank is unconvinced Marvin is dead, Sarah convinces him to attend Marvin's funeral where he delivers a tearful eulogy. Government agents interrogate Frank at an FBI Yankee White facility. Corrupt agent Jack Horton and a team of private military contractors ambush the facility; he threatens to torture Sarah until Frank gives him the information he needs. Frank evades Horton, and with the help of the still living Marvin, goes on the run with Sarah.
Marvin explains he and Frank have been targeted as members of Operation Nightshade, a clandestine operation during the Cold War to smuggle a nuclear weapon into Russia. Horton convinces international agencies that Frank and his associates are terrorists on the run. Frank's old ally Victoria notifies him that she has been contracted by MI6 to kill the fugitives. Another top contract killer, Han Cho-Bai, is also hired, seeking revenge against Frank.
Frank, Marvin, and Sarah steal Han's plane and fly to Paris to find "The Frog", with the Americans and Han in pursuit.

They interrogate the Frog and Sarah, hoping to one-up Katja, seduces him.

question:
Passage: By 1930, Szigeti was established as a major international concert violinist. He performed extensively in Europe, the United States and Asia, and made the acquaintance of many of the era's leading instrumentalists, conductors and composers.
In 1939, to escape the war and Nazi persecution of the Jews, Szigeti emigrated with his wife to the United States, where they settled in California. (A year later, Bartók also fled to America, and just two days after his arrival, he and Szigeti played a sonata recital at the Library of Congress in Washington, D.C.)During the 1930s, 1940s and into the 1950s, Szigeti recorded extensively, leaving a significant legacy.  Notable recordings include the above-mentioned Library of Congress sonata recital; the studio recording of Bartók's Contrasts with Benny Goodman on clarinet and the composer at the piano; the violin concertos of Beethoven, Brahms, Mendelssohn, Prokofiev (No. 1) and Bloch under the batons of such conductors as Bruno Walter, Hamilton Harty and Sir Thomas Beecham; and various works by J.S. Bach, Busoni, Corelli, Handel and Mozart. One of his last recordings was of the Six Sonatas and Partitas for solo violin by Bach; although his technique had deteriorated noticeably by that time, the recording is prized for Szigeti's insight and depth of interpretation.In 1950, Szigeti was detained at Ellis Island upon returning from a European concert tour and was held for several days, officially "temporarily excluded" from the country. The reasons for his detention remain unclear. The following year, he became a naturalized American citizen. 
Question: What is the name of the person that made a noble recording of Busoni?
answer:

Szigeti.
