Problem: Background: Def Leppard are an English rock band formed in 1977 in Sheffield as part of the new wave of British heavy metal movement. Since 1992, the band has consisted of Joe Elliott (lead vocals), Rick Savage (bass, backing vocals), Rick Allen (drums, backing vocals), Phil Collen (lead and rhythm guitar, backing vocals), and Vivian Campbell (rhythm and lead guitar, backing vocals). This is the band's longest lasting line-up. The band's strongest commercial success came between the early 1980s and the early 1990s.
Context: On 5 September 2000, Def Leppard were inducted into the Rock Walk of Fame on Hollywood's Sunset Boulevard by their friend Brian May of Queen. In 2001, VH1 produced and aired Hysteria - The Def Leppard Story, a biopic that included Anthony Michael Hall as Mutt Lange and Amber Valletta as Lorelei Shellist (Steve Clark's girlfriend). The docudrama covered the band's history between 1977 through 1986, recounting the trials and triumphs of Rick Allen and Steve Clark. 18 July broadcast still produced some of the channel's highest-ever ratings and is available on DVD. Def Leppard's tenth album, X, saw the band's musical direction moving more towards pop and further away from the band's hard rock roots. X quickly disappeared from the charts, ultimately becoming the band's least successful release. However, the accompanying tour played to the band's strongest audiences since Adrenalize. An expanded and updated best-of collection, Best Of, was released internationally in October 2004. The North America-only version, Rock of Ages - The Definitive Collection, was released the following May. Def Leppard participated at the Live 8 show in Philadelphia and toured in the summer with Bryan Adams. In 2005, the band left their longtime management team, Q-Prime, and signed with HK Management. On 23 May 2006, Def Leppard released an all-covers album titled Yeah!. The disc pays homage to classic rock songs of their childhood, originally recorded by Blondie, The Kinks, Sweet, ELO, and Badfinger among others. It debuted at No. 16 in the US, their tenth consecutive Top 20 album. The band, along with Queen, Kiss, and Judas Priest, were the inaugural inductees of VH1 Rock Honors on 31 May 2006. During the show, The All-American Rejects paid homage to the band with a cover of "Photograph". Soon afterwards, they embarked on a US tour with Journey. That October, Hysteria was re-released in a two-disc deluxe edition format, which combined the original remastered album with b-sides, remixes, and bonus tracks from single releases. Def Leppard began their "Downstage Thrust Tour", on 27 June, which took them across the US and into Canada. Support bands were Foreigner and Styx.
Question: Who was still left in the band in these years?
Answer:

Problem: Background: Andrew "Rube" Foster (September 17, 1879 - December 9, 1930) was an American baseball player, manager, and executive in the Negro leagues. He was elected to the Baseball Hall of Fame in 1981. Foster, considered by historians to have been perhaps the best African-American pitcher of the first decade of the 1900s, also founded and managed the Chicago American Giants, one of the most successful black baseball teams of the pre-integration era. Most notably, he organized the Negro National League, the first long-lasting professional league for African-American ballplayers, which operated from 1920 to 1931.
Context: In 1907, Foster's manager Sol White published his Official Baseball Guide: History of Colored Baseball, with Foster contributing an article on "How to Pitch." However, before the season began, he and several other stars (including, most importantly, the outfielder Pete Hill) left the Philadelphia Giants for the Chicago Leland Giants, with Foster named playing manager. Under his leadership, the Lelands won 110 games (including 48 straight) and lost only ten, and took the Chicago City League pennant. The following season the Lelands tied a national championship series with the Philadelphia Giants, each team winning three games. Foster suffered a broken leg in July 1909, but rushed himself back into the lineup in time for an October exhibition series against the Chicago Cubs. Foster, pitching the second game, squandered a 5-2 lead in the ninth inning, then lost the game on a controversial play when a Cubs runner stole home while Foster was arguing with the umpire. The Lelands lost the series, three games to nothing. The Lelands also lost the unofficial western black championship to the St. Paul Colored Gophers. In 1910, Foster wrested legal control of the team from its founder, Frank Leland. He proceeded to put together the team he later considered his finest. He signed John Henry Lloyd away from the Philadelphia Giants; along with Hill, second baseman Grant Johnson, catcher Bruce Petway, and pitchers Frank Wickware and Pat Dougherty, Lloyd sparked the Lelands to a 123-6 record (with Foster himself contributing a 13-2 record on the mound).
Question: How long was he manager?
Answer: In 1910, Foster wrested legal control of the team from its founder, Frank Leland. He proceeded to put together the team he later considered his finest.

Problem: Background: Daniel Lee Dierdorf (born June 29, 1949) is a former American football offensive lineman and current sportscaster. A native of Canton, Ohio, Dierdorf played college football for the University of Michigan from 1968 to 1970 and was selected as a consensus first-team All-American in 1970 and a first-team All-Big Ten Conference player in 1969 and 1970. He was inducted into the University of Michigan Athletic Hall of Honor in 1996 and the College Football Hall of Fame in 2000. Dierdorf played professional football in National Football League (NFL) with the St. Louis Cardinals for 13 seasons from 1971 to 1983.
Context: On September 9, 1979, Dierforf sustained torn ligaments in his left knee during an extra point attempt in the second quarter of the second game of the season against the New York Giants. After the game, Dierdorf said, "The knee was completely out of the socket. It moved a couple of inches off to the side. My leg was all twisted around and my foot was pointing in the wrong direction. It was painful. Very painful." Dierdorf was carried off the field on a stretcher, underwent knee surgery, and missed the remainder of the 1979 season. Dierdorf returned to the Cardinals in 1980, starting all 16 games for the team at right tackle in both the 1980 and 1981 seasons. In 1980, he was selected to play in the Pro Bowl and was selected as a first-team All-NFL player by the NEA. In 1982, Dierdorf moved to center and was the starter at that position for all nine games in a strike-shortened season. In 1983, Dierdorf returned to his right tackle position and appeared in seven games, only four as a starter. On October 11, 1983, after the Cardinals began the season with a 1-5 record, Dierdorf announced that he would retire at the end of the 1983 season. At the press conference announcing his retirement, Dierdorf said, "This was an easy decision for me to make. . . . Physically, I just can't play the type of game I want to." He added: "Ninety-five percent of me is sad that I'm retiring, but my knees are very, very happy."
