Problem: Background: Augusto Jose Ramon Pinochet Ugarte (; Spanish: [au'gusto pino'(t)Se, -'(t)Set]; 25 November 1915 - 10 December 2006) was a Chilean general, politician and the dictator of Chile between 1973 and 1990 who remained the Commander-in-Chief of the Chilean Army until 1998 and was also President of the Government Junta of Chile between 1973 and 1981. Pinochet assumed power in Chile following a United States-backed coup d'etat on 11 September 1973 that overthrew the democratically elected socialist Unidad Popular government of President Salvador Allende and ended civilian rule.
Context: On 11 September 1973, the combined Chilean Armed Forces (the Army, Navy, Air Force, and Carabineros) overthrew Allende's government in a coup, during which the presidential palace, La Moneda, was shelled and Allende committed suicide. While the military claimed that he had committed suicide, controversy surrounded Allende's death, with many claiming that he had been assassinated (theory discarded by the Chilean Supreme Court in 2014).  In his memoirs Pinochet said that he was the leading plotter of the coup and had used his position as commander-in-chief of the Army to coordinate a far-reaching scheme with the other two branches of the military and the national police. In later years, however, high military officials from the time have said that Pinochet reluctantly became involved only a few days before the coup was scheduled to occur, and followed the lead of the other branches (especially the Navy, under Merino) as they executed the coup.  The new government rounded up thousands of people and held them in the national stadium where many were killed. This was followed by brutal repression during Pinochet's rule, during which about 3,000 people were killed, and more than 1,000 are still missing.  In the months that followed the coup, the junta, with authoring work by historian Gonzalo Vial and admiral Patricio Carvajal, published a book titled El Libro Blanco del cambio de gobierno en Chile (commonly known as El Libro Blanco, "The White Book on the Change of Government in Chile"), where they said that they were in fact anticipating a self-coup (the alleged Plan Zeta, or Plan Z) that Allende's government or its associates were purportedly preparing. United States intelligence agencies believed the plan to be untrue propaganda. Although later discredited and officially recognized as the product of political propaganda, Gonzalo Vial insists in the similarities between the alleged Plan Z and other existing paramilitary plans of the Popular Unity parties in support of its legitimacy.  Canadian Jean Charpentier of Television de Radio-Canada was the first foreign journalist to interview General Pinochet following the coup.

Background: Born in Prague, Czech Republic (then part of the Austro Hungarian empire) Friml showed aptitude for music at an early age. He entered the Prague Conservatory in 1895, where he studied the piano and composition with Antonin Dvorak. Friml was expelled from the conservatory in 1901 for performing without permission.
Context: Friml wrote his most famous operettas in the 1920s. In 1924, he wrote Rose-Marie. This operetta, on which Friml collaborated with lyricists Oscar Hammerstein II and Otto Harbach and co-composer Herbert Stothart, was a hit worldwide, and a few of the songs from it also became hits including "The Mounties" and "Indian Love Call". The use of murder as part of the plot was ground-breaking among operettas and musical theatre pieces at the time.  After Rose-Marie's success came two other hit operettas, The Vagabond King in 1925, with lyrics by Brian Hooker and William H. Post, and The Three Musketeers in 1928, with lyrics by P. G. Wodehouse and Clifford Grey, based on Alexandre Dumas's famous swashbuckling novel. In addition, Friml contributed to the Ziegfeld Follies of 1921 and 1923.  Friml wrote music for many films during the 1930s, often songs adapted from previous work. The Vagabond King, Rose-Marie and The Firefly were all made into films and included at least some of Friml's music. Oddly enough, his operetta version of The Three Musketeers was never filmed, despite the fact that the novel itself has been filmed many times. In 1930, he wrote a new operetta score for film, The Lottery Bride. Like his contemporary, Ivor Novello, Friml was sometimes ridiculed for the sentimental and insubstantial nature of his compositions and was often called trite. Friml was also criticized for the old-fashioned, Old World sentiments found in his works. Friml's last stage musical was Music Hath Charms in 1934. During the 1930s, Friml's music fell out of fashion on Broadway and in Hollywood.
