Problem: Background: Paul Vaughn Butterfield (December 17, 1942 - May 4, 1987) was an American blues harmonica player and singer. After early training as a classical flautist, he developed an interest in blues harmonica. He explored the blues scene in his native Chicago, where he met Muddy Waters and other blues greats, who provided encouragement and opportunities for him to join in jam sessions. He soon began performing with fellow blues enthusiasts Nick Gravenites and Elvin Bishop.
Context: Butterfield was born in Chicago and raised in the city's Hyde Park neighborhood. The son of a lawyer and a painter, he attended the University of Chicago Laboratory Schools, a private school associated with the University of Chicago. Exposed to music at an early age, he studied classical flute with Walfrid Kujala, of the Chicago Symphony Orchestra. Butterfield was also athletic and was offered a track scholarship to Brown University. However, a knee injury and a growing interest in blues music sent him in a different direction. He met guitarist and singer songwriter Nick Gravenites, who shared an interest in authentic blues music. By the late 1950s, they were visiting blues clubs in Chicago, where musicians such as Muddy Waters, Howlin' Wolf, Little Walter, and Otis Rush, encouraged them and occasionally let them sit in on jam sessions. The pair were soon performing as Nick and Paul in college-area coffee houses.  In the early 1960s, Butterfield met aspiring blues guitarist Elvin Bishop. Bishop recalled:  He [Butterfield] was playing more guitar than harp when I first met him. But in about six months he became serious about the harp, and he seemed to get about as good as he got in that six months. He was just a natural genius. This was in 1960 or 1961. By this time Butter had been hanging out in the ghetto for a couple of years, and he was part of the scene and getting accepted.  Eventually, Butterfield, on vocals and harmoica, and Bishop, accompanying him on guitar, were offered a regular gig at Big John's, a folk club in the Old Town district on Chicago's North Side. With this booking, they persuaded bassist Jerome Arnold and drummer Sam Lay (both from Howlin' Wolf's touring band) to form a group with them in 1963. Their engagement at the club was highly successful and brought the group to the attention of record producer Paul A. Rothchild.

Problem: Background: Judas Priest are an English heavy metal band formed in West Bromwich in 1969. The band have sold over 50 million copies of their albums to date. They are frequently ranked as one of the greatest metal bands of all time. Despite an innovative and pioneering body of work in the latter half of the 1970s, the band struggled with indifferent record production, repeated changes of drummer, and lack of major commercial success or attention until 1980, when they adopted a more simplified sound on the album British Steel, which helped shoot them to rock superstar status.
Context: Judas Priest went into the studio in June-July 1974 with Black Sabbath producer Rodger Bain. The band released their debut single "Rocka Rolla" that August and followed in September with an album of the same name. The album features a variety of styles--straight-up rock, heavy riffing, and progressive.  Technical problems during the recording contributed to the poor sound quality of the record. Producer Rodger Bain, whose resume included Black Sabbath's first three albums as well as Budgie's first album, dominated the production of the album and made decisions with which the band did not agree. Bain also chose to leave fan favourites from the band's live set, such as "Tyrant", "Genocide" and "The Ripper", off the album and he cut the song "Caviar and Meths" from a 10-minute song down to a 2-minute instrumental.  The tour for Rocka Rolla was Judas Priest's first international tour with dates in Germany, the Netherlands, Norway and Denmark including one show at Hotel Klubben in Tonsberg, one hour from Oslo, Norway, which scored them a somewhat negative review in the local press. The album flopped upon release, leaving Priest in dire financial straits. Priest attempted to secure a deal with Gull Records to get a monthly pay of 50 pounds, however, because Gull Records were struggling as well, they declined. Rocka Rolla (1974) has been for the most part dismissed by the band and none of its songs were played live after 1976 except for "Never Satisfied", which was revived during the Epitaph Tour in 2011.
Question: What were some of the other songs on the album?
Answer: "Tyrant", "Genocide" and "The Ripper",

Problem: Background: Giulio Andreotti  (Italian: ['dZu:ljo andre'otti]; 14 January 1919 - 6 May 2013) was an Italian politician and statesman who served as the 41st Prime Minister of Italy and leader of the Christian Democracy party; he was the sixth longest-serving Prime Minister since the Italian Unification and the second longest-serving post-war Prime Minister, after Silvio Berlusconi. Andreotti is widely considered the most powerful and prominent politician of the so-called First Republic. Beginning as a protege of Alcide De Gasperi, Andreotti achieved cabinet rank at a young age and occupied all the major offices of state over the course of a forty-year political career, being seen as a reassuring figure by the civil service, business community, and Vatican. In foreign policy, he guided Italy's European Union integration, and established closer relations with the Arab world.
Context: Andreotti did not shine at his school and started work in a tax office while studying law at the University of Rome. In this period he became a member of the Italian Catholic Federation of University Students (FUCI), the only non-fascist youth organization which was allowed by the regime of Benito Mussolini. Its members included many of the future leaders of the Italian Christian Democracy.  In 1938 while researching the papal navy in the Vatican library, he met Alcide De Gasperi, who had been given sanctuary by the Pope. De Gasperi asked Andreotti if he had nothing better to do with his time, inspiring him to become politically active. Speaking of De Gasperi, Andreotti said, "He taught us to search for compromise, to mediate."  In July 1939, while Aldo Moro was president of FUCI, Andreotti became director of its magazine Azione Fucina. In 1942, when Moro was enrolled in the Italian Army, Andreotti succeeded him as president of FUCI, a position he held until 1944. During his early years Andreotti suffered violent migraines that forced him to sporadically make use of psychoactive drugs and opiates. During World War II, Andreotti wrote for the Rivista del Lavoro, a fascist propaganda publication, but was also a member of the then-clandestine newspaper Il Popolo.  In July 1943, Andreotti contributed, along with Mario Ferrari Aggradi, Paolo Emilio Taviani, Guido Gonella, Giuseppe Capograssi, Ferruccio Pergolesi, Vittore Branca, Giorgio La Pira, Giuseppe Medici and Moro, to the creation of the Code of Camaldoli, a document planning of economic policy drawn up by members of the Italian Catholic forces. The Code served as inspiration and guideline for economic policy of the future Christian Democrats. In 1944 he became a member of the National Council of the newborn Christian Democracy party, and after the end of the conflict he became responsible for the youth organization of the party.
Question: what did he do for the youth organization?
