Question: "The Sacred War", was one of the most famous Soviet songs of the Second World War, the music is by Aleksandr Aleksandrov, founder of the Alexandrov Ensemble, an official army choir of which armed forces?
Context: "My Army" (Russian: Армия моя ) is a Soviet marching song written in the Russian language, performed by the Alexandrov Ensemble.  The lyrics were written by Soviet musician and composer Рафаэль Морицович Плаксин (Rafael Moritsovich Plaksin).  The music was composed by prolific Soviet composer Александр Александрович Абрамов (Aleksandr Aleksandrovich Abramov), in 1970. Boris Alexandrovich Alexandrov (Russian: Борис Александрович Александров , August 4, 1905 Bologoye – June 17, 1994 Moscow) was a Soviet Russian composer, and, from 1946 to 1986, the second head of the Alexandrov Ensemble which was founded by his father, Alexander Vasilyevich Alexandrov.  Alexandrov reached the rank of Major-General and was awarded the order of Hero of Socialist Labour, the Lenin Prize and the State Prize of the USSR, and named People's Artist of the USSR.  Music by Alexandrov is used for the Anthem of Transnistria. Soyuz TM-3 was the third manned spacecraft to visit the Soviet space station Mir, following Soyuz-T15 and Soyuz-TM2.  It was launched in July 1987, during the long duration expedition Mir EO-2, and acted as a lifeboat for the second segment of that expedition.  There were three people aboard the spacecraft at launch, including the two man crew of the week-long mission Mir EP-1, consisting of Soviet cosmonaut Alexander Viktorenko and Syrian Muhammed Faris.  Faris was the first Syrian to travel to space, and as of November 2010, the only one.  The third cosmonaut launched was Aleksandr Aleksandrov, who would replace one of the long duration crew members Aleksandr Laveykin of Mir EO-2.  Laveykin had been diagnosed by ground-based doctors to have minor heart problems, so he returned to Earth with the EP-1 crew in Soyuz TM-2. "The Sacred War" (Russian: Священная война "Svyashchennaya Voyna", also known as Вставай, страна огромная!  "Vstavaj, strana ogromnaja", "Arise, Great (Vast) Country!")  was one of the most famous Soviet songs of the Second World War.  The music is by Aleksandr Aleksandrov, founder of the Alexandrov Ensemble and the music composer for the National Anthem of the Soviet Union.  The lyrics are by Vasily Lebedev-Kumach. The Red Army Choir MVD Ensemble is an official academic ensemble of the Ministry of the Interior of the Russian Federation.  Established in 1939, the ensemble carries on the tradition of choirs and ballets of the Soviet Red Army, with singers, musicians and dancers.  MVD Ensemble and Alexandrov Ensemble are the only groups with the right to claim the title "Red Army Choir". The Alexandrov Ensemble (commonly known as the Red Army Choir in the West) is an official army choir of the Russian armed forces.  Founded during the Soviet era, the ensemble consists of a male choir, an orchestra, and a dance ensemble. Mir EO-2 (also called Mir Principal Expedition 2) was the second long duration expedition to the Soviet space station Mir, and it lasted from February to December 1987.  The mission was divided into two parts (sometimes called (a) and (b)), the division occurring when one of the two crew members, Aleksandr Laveykin, was replaced part way through the mission by Aleksandr Aleksandrov.  Laveykin was replaced because ground-based doctors had diagnosed him with minor heart problems. The Song of the Soviet Army (Russian: Песня о Советской Армии , "Pesnya o Sovetskoj Armii" ) or Invincible and Legendary (Несокрушимая и легендарная ) was a famous World War II song written and performed at the war's end.  Its performance was done by numerous artists, including the Alexandrov Ensemble.  The original 1945 is highly triumphal with its brass fanfares and ecstatic chords extended upward with the aid of trumpets, as part of the V-E Day celebrations.  That arrangement by A. Alexandrov is very much in the tradition of final choruses in 19th-century Italian grand opera, and shows how he originally envisaged this composition.  There are many versions of the song. Roads or The Roads (Russian: Дороги) is a Soviet WWII song by Anatoly Novikov to lyrics by the poet Lev Ivanovich Oshanin.  The song is one of the best known works of the composer, having been popularised by both ensembles carrying the name of the Red Army Choir, namely the Alexandrov Ensemble and MVD Ensemble.  Novikov and Oshanin were members of a military troupe at the front and the song was composed under artillery fire at Zhizdra.  Among those who have recorded the song are Muslim Magomayev, Ivan Rebroff (1986), Dmitri Hvorostovsky on the war songs album "Where Are You My Brothers", and the Choir of Sretensky Monastery.  The song begins "Ah roads. ."  («Эх, дороги…») and is not to be confused with another Red Army Choir favourite "На дороге" ("On the road") or "Гей по дароге". Alexander Vasilyevich Alexandrov (Russian: Александр Васильевич Александров , "Aleksandr Vasilevich Aleksandrov") (13 April [O.S. 1 April] 1883 – 8 July 1946) was a Russian Soviet composer, the founder of the Alexandrov Ensemble, who wrote the music for the State Anthem of the Soviet Union, which, in 2000, became the national anthem of Russia (with new lyrics).  During his career, he also worked as a professor of the Moscow State Conservatory, and became a Doctor of Arts.  His work was recognized by the awards of the title of People's Artist of the USSR and the Stalin Prize.
