Passage: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Mühlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskönig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Köthen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Köthen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134. 
Question: What is the last name of the person who parodied some secular cantatas as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134?
answer:
Bach.

Passage: As a young boy, after his mother dies, Rick Martin sees a trumpet in the window of a pawn shop. He works in a bowling alley to save up enough money to buy it. Rick grows up to be an outstanding musician (adult Rick played by Kirk Douglas), tutored by jazzman Art Hazzard. He lands a job playing for the big band of Jack Chandler, getting to know the piano player Smoke Willoughby and the beautiful singer Jo Jordan.
Chandler orders him to always play the music exactly as written. Rick prefers to improvise, and one night, during a break with Chandler's band, he leads an impromptu jam session, which gets him fired.
Jo has fallen for Rick and finds him a job in New York with a dance orchestra. One night, her friend Amy North accompanies her to hear Rick play. Amy, studying to be a psychiatrist, is a complicated young woman still disturbed by her own mother's suicide.
She claims to be incapable of feeling love, but she and Rick begin an affair, which consumes him so completely he begins to slip away from his old friends. Jo eventually tries to warn him against getting too involved with Amy, suggesting that she will hurt him because "way inside she's all mixed up"; but Amy arrives while Jo is talking to Rick, and it is revealed that the two are already married. Jo hopes he will forgive her words. 
Question: What is the full name of the person that the jazzman tutors?

question:
Passage: Elvira Kent and her husband Michael suspect each other of cheating. For their wedding anniversary, Elvira books an ocean cruise to Rio de Janeiro but  her husband claims that unexpected business will prevent him from going. Seeing an opportunity, Elvira pretends to take the trip alone, but in fact sends singer Georgia Garrett, a woman she'd met at the travel agency, in her place and under her name. By secretly staying behind, Elvira hopes to find out if Michael is indeed sneaking around behind her back. Michael, however, is suspicious over Elvira's supposed willingness to go on the trip alone, and so hires private detective Peter Virgil to see if she is sneaking around behind his back.
Peter joins the cruise and, as part of his job, becomes acquainted with Georgia. Georgia, following the instructions of the real Elvira, keeps up the ruse by pretending to be Elvira to everyone, including Peter. Georgia and Peter are attracted to each other and gradually fall in love, which causes conflict for both of them.
During one of the cruise stops, Georgia's friend, Oscar Farrar, comes on board. Oscar is in love with Georgia despite Georgia's lack of interest in him, and when Peter spots them together, he thinks he has discovered the identity of Elvira's lover.
The film's third act is set in a Rio hotel, where all the principal characters converge and ride a merry-go-round of mistaken identities. Sorting out their true identities, resolving the crossed love plots, concludes the picture. 
Question: What is the full name of the person who thinks they have discovered the identity of someone's lover?
answer:

Peter Virgil.
