input: Until 1963 peers could not disclaim their peerage in order to sit in the House of Commons, and thus a peerage was sometimes seen as an impediment to a future political career.  In 1999, the House of Lords Act abolished the automatic right of hereditary peers to sit in the House of Lords. Out of about 750 hereditary peers, only 92 may sit in the House of Lords. The Act provides that 90 of those 92 seats are to be elected by other members of the House: 15 by vote of the whole house (including life peers), 42 by the Conservative hereditary peers, two by the Labour hereditary peers, three by the Liberal Democrat hereditary peers, and 28 by the crossbench hereditary peers. Elections were held in October and November 1999 to choose those initial 90 peers, with all hereditary peers eligible to vote. Hereditary peers elected hold their seats until their death, resignation or exclusion for non-attendance (the latter two means introduced by the House of Lords Reform Act 2014), at which point by-elections are held to maintain the number at 92.  The remaining two hold their seats by right of the hereditary offices of Earl Marshal and Lord Great Chamberlain. These offices are hereditary in themselves, and in recent times have been held by the Dukes of Norfolk and the Marquesses of Cholmondeley respectively. These are the only two hereditary peers whose right to sit is automatic.  The Government reserves a number of political and ceremonial positions for hereditary peers. To encourage hereditary peers in the House of Lords to follow the party line, a number of Lords-in-Waiting (government whips) are usually hereditary peers. This practice was not adhered to by the Labour government of 1997-2010 due to the small number of Labour hereditary peers in the House of Lords.

Answer this question "How was it seen as an impediment?"
output: Hereditary peers elected hold their seats until their death, resignation or exclusion for non-attendance

Problem: Background: Armando Anthony "Chick" Corea (born June 12, 1941) is an American jazz pianist/electric keyboardist and composer. His compositions "Spain", "500 Miles High", "La Fiesta" and "Windows", are considered jazz standards. As a member of Miles Davis's band in the late 1960s, he participated in the birth of jazz fusion. In the 1970s he formed the fusion band Return to Forever.
Context: In the 1970s Corea started working with vibraphonist Gary Burton, with whom he recorded several duet albums for ECM, including 1972's Crystal Silence. They reunited in 2006 for a concert tour. A new record called The New Crystal Silence was issued in 2008 and won a Grammy Award in 2009. The package includes a disc of duets and another disc with the Sydney Symphony Orchestra.  Toward the end of the 1970s, Corea embarked on a series of concerts and two albums with Hancock. These concerts were presented in elegant settings with both pianists dressed formally and performing on Yamaha concert grand pianos. The two traded playing each other's compositions, as well as pieces by other composers such as Bela Bartok. In 1982, Corea performed The Meeting, a live duet with the classical pianist Friedrich Gulda.  In December 2007 Corea recorded a duet album, The Enchantment, with banjoist Bela Fleck. Fleck and Corea toured extensively for the album in 2007. Fleck was nominated in the Best Instrumental Composition category at the 49th Grammy Awards for the track "Spectacle".  In 2008 Corea collaborated with Japanese pianist Hiromi Uehara on the live album Duet (Chick Corea and Hiromi). The duo played a concert at Tokyo's Budokan arena on April 30.  In 2015 Corea reprised the duet concert series with Hancock, again sticking to a dueling-piano format, though both also had synthesizers at their station. The first concert in this series was played at the Paramount Theatre in Seattle, and featured improvised music along with iconic songs from each of the duo and standards from other composers.
Question: Who did he perform concerts with?
Answer: Toward the end of the 1970s, Corea embarked on a series of concerts and two albums with Hancock.

Question: KAT-TUN (katoun, Katun) is a Japanese boy band formed under Johnny & Associates (Johnny's) in 2001. The group's name was originally an acronym based on the first letter of each member's family name: Kazuya Kamenashi, Jin Akanishi, Junnosuke Taguchi, Koki Tanaka, Tatsuya Ueda, and Yuichi Nakamaru. Their debut on March 22, 2006 was marked by a tripartite release of a CD single, album and music DVD on their exclusive record label J-One Records. Since then, all of their single, album and music DVD releases have debuted at number one on the Oricon music and DVD charts.

On March 22, KAT-TUN released their debut single "Real Face", accompanied by an album, Best of KAT-TUN and a DVD Real Face Film. These were released on their own label J-One Records. The group also went on a nationwide tour, Live of KAT-TUN "Real Face", in support of the album. Within the first week, Best of KAT-TUN, "Real Face" and Real Face Film topped all three Oricon weekly charts by selling 556,548 copies, 754,234 copies and 374,202 copies respectively. They became the second artists to do so, the first being Ayumi Hamasaki. With these numbers, KAT-TUN holds the record for the highest weekly single debut sales (previously held by Arashi with their debut single "Arashi" of 557,000 copies sold in 1999). In addition, "Real Face" topped the Oricon charts for three weeks straight, becoming the first debut single to do so in Japan in 8 years 8 months since KinKi Kids' debut single "Garasu no Shonen." The single sold over a million copies in nine weeks, making "Real Face" the highest selling single for the year 2006.  In March 2006, KAT-TUN became the first group to hold their own performances in Japan's most popular stadium, Tokyo Dome, before debuting. They performed to 110,000 people over two days and about 630,000 people in total during the tour. About three months after releasing "Real Face", KAT-TUN released their second single, "Signal", on July 19.  On October 12, member Akanishi announced a hiatus from the group in order to study linguistics abroad in the United States, leaving KAT-TUN as a five-member group for six months. The remaining members continued activities by releasing their third single, "Bokura no Machi de" as the theme song to members Kamenashi and Tanaka's drama, Tatta Hitotsu no Koi and their second album, Cartoon KAT-TUN II You on December 7.  KAT-TUN is the first group in Japan to have all three singles from debut to exceed 500,000 in yearly sales, taking first, fifth and thirteenth place on the Oricon yearly singles chart.
