Problem: Background: MC5 was an American rock band from Lincoln Park, Michigan, formed in 1964. The original band line-up consisted of vocalist Rob Tyner, guitarists Wayne Kramer and Fred "Sonic" Smith, bassist Michael Davis, and drummer Dennis Thompson. "Crystallizing the counterculture movement at its most volatile and threatening", according to AllMusic critic Stephen Thomas Erlewine, the MC5's leftist political ties and anti-establishment lyrics and music positioned them as emerging innovators of the punk movement in the United States.
Context: The origins of MC5 can be traced to the friendship between guitarists Wayne Kramer and Fred Smith. Friends since their teen years, they were both fans of R&B music, blues, Chuck Berry, Dick Dale, The Ventures, and what would later be called garage rock: they adored any music with speed, energy and a rebellious attitude. Each guitarist/singer formed and led a rock group (Smith's Vibratones and Kramer's Bounty Hunters). As members of both groups left for college or straight jobs, the most committed members eventually united (under Kramer's leadership and the "Bounty Hunters" name) with Billy Vargo on guitar and Leo LeDuc on drums (at this point Smith played bass), and were popular and successful enough in and around Detroit that the musicians were able to quit their day jobs and make a living from the group.  Kramer felt they needed a manager, which led him to Rob Derminer, a few years older than the others, and deeply involved in Detroit's hipster and left-wing political scenes. Derminer originally auditioned as a bass guitarist (a role which he held briefly in 1964, with Smith switching to guitar to replace Vargo and with Bob Gaspar replacing LeDuc), though they quickly realized that his talents could be better used as a lead singer: Though not conventionally attractive and rather paunchy by traditional frontman standards, he nonetheless had a commanding stage presence, and a booming baritone voice that evidenced his abiding love of American soul and gospel music. Derminer renamed himself Rob Tyner (after Coltrane's pianist McCoy Tyner). Tyner also invented their new name, MC5: it reflected their Detroit roots (it was short for "Motor City Five'). In some ways the group was similar to other garage bands of the period, composing soon-to-be historic workouts such as "Black to Comm" during their mid-teens in the basement of the home of Kramer's mother. Upon Tyner's switch from bassist to vocalist, he was initially replaced by Patrick Burrows, however the lineup was stabilised in 1965 by the arrival of Michael Davis and Dennis Thompson to replace Burrows and Gaspar respectively.  The music also reflected Smith and Kramer's increasing interest in free jazz--the guitarists were inspired by the likes of Albert Ayler, Archie Shepp, Sun Ra and late period John Coltrane, and tried to imitate the ecstatic sounds of the squealing, high-pitched saxophonists they adored. MC5 even later opened for a few U.S. midwest shows for Sun Ra, whose influence is obvious in "Starship". Kramer and Smith were also deeply inspired by Sonny Sharrock, one of the few electric guitarists working in free jazz, and they eventually developed a unique interlocking style that was like little heard before: Kramer's solos often used a heavy, irregular vibrato, while Smith's rhythms contained an uncommon explosive energy, including patterns that conveyed great excitement, as evidenced in "Black to Comm" and many other songs.

Problem: Background: Conacher was born in Toronto, Ontario on May 24, 1900. His middle name was given after the South African city of Pretoria, where British troops were fighting the Boer War at the time of his birth. He was the eldest son of Benjamin and Elizabeth Conacher, and the third of ten children overall. He had four brothers and five sisters.
Context: Conacher scored the first goal in Pirates history on American Thanksgiving Day Thursday November 26, 1925, against the Boston Bruins. He scored nine goals in 33 games in 1925-26, then returned to Toronto to play professional baseball with the Toronto Maple Leafs. An outfielder on the team, Conacher and the Maple Leafs won the International League championship then defeated the Louisville Colonels to win the Little World Series.  He returned to Pittsburgh for the 1926-27 NHL season, but was dealt early in the year to the New York Americans in exchange for Charlie Langlois and $2,000. The trade nearly proved disastrous for Conacher. He scored 8 goals in 1926-27 and improved to 11 in 1927-28, but playing for a team owned by notorious bootlegger Bill Dwyer resulted in his becoming a heavy drinker. Conacher served as player-coach in 1929-30, but his play and health had deteriorated. Two events in that off-season saved Conacher: he swore off alcohol completely upon the birth of his first child, and his playing rights were sold to the Montreal Maroons.  Conacher periodically struggled with Montreal, and at one point was placed on waivers with no other team willing to take over his contract. Nonetheless, his overall play and point totals increased for three consecutive seasons with the Maroons, peaking at 28 points in 1932-33. He was named to the Second All-Star Team that season, but was traded to the Chicago Black Hawks in exchange for Teddy Graham. Conacher was a key figure in the club's first-ever Stanley Cup victory that season. He finished second to the Canadiens' Aurel Joliat in the voting for the Hart Trophy and earned a spot on the NHL's First All-Star Team.  On Wednesday October 3, 1934, Conacher was involved in one of the largest transactions in league history. He was dealt to the Montreal Canadiens, along with Leroy Goldsworthy and Roger Jenkins in exchange for Montreal superstar Howie Morenz, Lorne Chabot and Marty Burke. The deal was only part of a series of trades involving four teams that represented one of the biggest deals in NHL history. Immediately following the Chicago trade, Conacher was sent back to the Maroons, along with Herb Cain, in exchange for the rights to Nelson Crutchfield. Conacher spent his last three NHL seasons with the Maroons and won his second Stanley Cup in 1935. He ended his hockey career after the team was eliminated from the playoffs by the New York Rangers on April 23, 1937. That final year he was runner-up to Babe Siebert in the 1937 Hart Trophy voting and was placed on the NHL Second All-Star Team.
Question: Did he retire?
Answer:
He ended his hockey career after the team was eliminated from the playoffs by the New York Rangers on April 23, 1937.
