[EX Q]: Question: In what year did Hellhammer become Celtic Frost? Passage 1:Welcome to Hell influenced several later bands. Venom's music helped shape the development of many thrash metal bands, specifically the "Big Four of Thrash" (who in turn were highly influential): Metallica, Slayer, Anthrax, and Megadeth (Metallica opened for Venom on an early 1980s tour, and Venom opened for Metallica and Slayer on the Ride the Lightning tour, and Slayer played with them and Exodus on the Combat Tour in 1985). Venom would also be of extreme importance to the black metal scene and even the early death metal scene, with numerous bands copying styles, themes, and imagery from the band, such as the Swiss band Hellhammer (later to become Celtic Frost), whom also helped pioneer the genres. Music critic Bradley Torreano wrote that Venom "caught the attention of both metalheads and punks, the band was emulated by the former and turned into camp icons by the latter." Henry Rollins once compared the band to Spinal Tap.
Passage 2:Duncan was born in Lebanon, Tennessee. His "paternal grandparents were small-areage farmers in Scott County, which in 1861 left Tennessee, refusing to follow the Volunteer State into the Confederacy, and declared itself 'the Free and Independent state of Scott.'" Duncan's parents were Lois (Swisher) and John Duncan Sr., who "hitchhiked into Knoxville with five dollars in his pocket,' and after an education at the University of Tennessee was elected mayor of Knoxville and then congressman." The elder Duncan was also a co-owner of the Knoxville Smokies of the "Sally League," for which his son "was a batboy, a ball shagger, scoreboard operator, and, as a freshman at the University of Tennessee, the Smokies' public-address announcer." Duncan also worked as a grocery bagger and salesman at Sears while working his way through school. Duncan supported Barry Goldwater's 1964 presidential campaign, and sent the first paycheck he earned as a bagboy at the local A&P to the Goldwater campaign.
Passage 3:Lynch first came to prominence on the inter-county scene as a member of the Cork senior football team in the late 1990s. He made his debut in the 199899 National Football League, a season which saw Cork reach the final of the competition. Dublin provided the opposition at Cork's home venue, Pairc Ui Chaoimh. A close game developed, however, Cork were never really troubled. A 012 to 17 score line resulted in victory for 'the Rebels', and gave Lynch a National League winners' medal in his debut season. Later that year he made his championship debut in the provincial series as Cork cruised to a Munster final showdown with arch-rivals Kerry. The men from 'the Kingdom' were on the hunt for a fourth successive provincial title, while Cork were out for success for the first time since 1995. Cork's victory on a score line of 210 to 24 was unexpected as Lynch claimed his very first Munster winners' medal. A subsequent defeat of Mayo saw Cork book their place in the All-Ireland final against Meath. The pressure was on the Cork footballers to secure a rare double, particularly since their hurling counterparts had won the All-Ireland title a fortnight previously. Ollie Murphy's first-half goal gave 'the Royals' a huge boost at half-time. Immediately after the interval Trevor Giles missed a penalty while Joe Kavanagh responded with a goal which gave Cork a brief lead. It was not enough as Lynch's side eventually lost the game by 111 to 18. In spite of this defeat Lynch was later rewarded with an All-Star award.
