Passage: In 1914 Tsarist Russia, Prince Peter Karagin is a captain of the Cossack Guards, riding home from manoeuvres to an evening of wine, women and song at St. Petersburg's Cafe Balalaika. The Balalaika's new star, Lydia Pavlovna Marakova, is blackmailed into attending the officers' party and is expected to choose a "favoured one." She intrigues Karagin when she makes good her escape instead.
Masquerading as a poor music student, Karagin insinuating himself into Lydia's family and circle of musician friends, unaware that they are dedicated revolutionaries. He discovers his larcenous orderly, Nikki Poppov, courting the Marakovs' maid, Masha. Karagin then bullies Ivan Danchenoff, Director of the Imperial Opera, into giving Lydia an audition; Danchenoff is pleasantly surprised to find that (unlike the 60 other women foisted on him by other aristocrats) she has real talent. Later, Karagin orders his usual arrangements for seduction, but falls in love instead and tries to cancel them. She understands both his former and current motives, and admits she loves him too. 
Question: What is the full name of the person Karagin falls in love with?
Lydia Pavlovna Marakova.

Passage: With the piece set to open on 26 December, Gilbert first read the libretto to the cast on 14 December, but Toole, who was playing the central role of Thespis, did not return from a tour of the British provinces until 18 December. He then appeared in nine performances at the Gaiety in the six days immediately after his return, and other actors had similar commitments. In addition, Hollingshead had committed the company to perform a pantomime at The Crystal Palace on 21 December, which included many of the performers who would be in Thespis. Lastly, Thespis was to play as the afterpiece to an H. J. Byron comedy, Dearer than Life, which shared many of its actors, including Toole and Fred Sullivan, and had to be rehearsed at the same time.Despite the short time available for rehearsals, Sullivan recalled that Gilbert insisted that the chorus play a major role, as it would do in their later Savoy operas:
Until Gilbert took the matter in hand choruses were dummy concerns, and were practically nothing more than a part of the stage setting. It was in 'Thespis' that Gilbert began to carry out his expressed determination to get the chorus to play its proper part in the performance. At this moment it seems difficult to realise that the idea of the chorus being anything more than a sort of stage audience was, at that time, a tremendous novelty. In consequence of this innovation, some of the incidents at the rehearsal of 'Thespis' were rather amusing. I remember that, on one occasion, one of the principals became quite indignant and said, 'Really, Mr. Gilbert, why should I stand here? I am not a chorus-girl!' to which Gilbert replied curtly, 'No, madam, your voice is not strong enough, or no doubt you would be.'. 
Question: What is the last name of the person who had an expressed determination to get the chorus to play its proper part in the performance?
Gilbert.

Passage: Sir Michael Kemp Tippett  (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the  Second World War. In his lifetime he was sometimes  ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio A Child of Our Time, the orchestral Fantasia Concertante on a Theme of Corelli, and the opera The Midsummer Marriage.
Tippett's talent developed slowly. He withdrew or destroyed his earliest compositions, and was 30 before any of his works were published. Until the mid-to-late 1950s his music was broadly lyrical in character, before changing to a more astringent and experimental style. New influences, including those of jazz and blues after his first visit to America in 1965, became increasingly evident in his compositions. While Tippett's stature with the public continued to grow, not all critics approved of these changes in style, some believing that the quality of his work suffered as a consequence. From around 1976 Tippett's late works began to reflect the works of his youth through a return to lyricism. Although he was much honoured in his lifetime, critical judgement on Tippett's legacy has been uneven, the greatest praise being generally reserved for his earlier works. His centenary in 2005 was a muted affair; apart from the few best-known works, his music has been performed  infrequently in the 21st century.
Having briefly embraced communism in the 1930s, Tippett avoided identifying with any political party. A pacifist after 1940, he was imprisoned in 1943 for refusing to carry out war-related duties required by his military exemption. His initial difficulties in accepting his  homosexuality led him in 1939 to Jungian psychoanalysis; the Jungian dichotomy of "shadow" and "light" remained a recurring factor in his music. He was a strong advocate of music education, and was active for much of his life as a radio broadcaster and writer on music. 
Question: What is the last name of the person whose music was broadly lyrical in character until the mid-to-late 1950s?

Tippett.
