Input: Consider Input: Question: How large was the endowment at Durham University the year that Mitchell started attending the school? Passage:Mitchell was born in London, and educated at Brightlands Preparatory School and Dulwich College, London. In 1943 he registered as a conscientious objector and his war-time service was spent in the Non-Combatant Corps. After the war, he taught at Oakfield Preparatory School, London and in 1947 founded and edited the journal Music Survey; several issues appeared before he was joined in 1949 by Hans Keller and the journal was re-launched in the Music Survey's so-called 'New Series' (194952), whose uncompromising critical standards and pugnaciously pro-Britten and pro-Schoenberg stance brought it renown and notoriety in equal measure. Mitchell studied at Durham University 1949-50. In the 1950s he was a regular contributor to the journals Musical Times and Musical Opinion. In 1958 he became editor of Music Books at Faber and Faber and in the same year was appointed Editor of Boosey & Hawkes's music journal Tempo, until 1962. From 1963 to 1964 he was a special music adviser at Boosey & Hawkes with particular responsibility for contemporary music and the acquisition of contemporary composers. He was responsible for Peter Maxwell Davies and Nicholas Maw joining the publisher's list. In 1965, with the encouragement of Benjamin Britten he founded the music-publishing firm of Faber Music, and was its first Managing Director (vice-chairman, 1976, chairman, 1977, president, 198895). In 1972 he became the first Professor of Music at Sussex University (until 1976). Following the death of Benjamin Britten, Mitchell became a senior trustee of the Britten-Pears Foundation; in 1986 he became the Foundation's director and chairman of the Britten Estate Ltd. From 1989 to 1992 he was chairman of the Performing Right Society. He was appointed a CBE in the 2000 New Year Honours, and died on 28 September 2017.

Input: Consider Input: Question: How long had Kortrijk been a team when Gillenken made his debut for OH Leuven? Passage:Gillekens made his debut for OH Leuven in the 201415 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 201415 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 201516 season, he did not play a single match that season. Following the relegation from the 201516 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 201617 season in the Belgian First Division B. During the winter 201718 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 201819 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.

Passage:In March 2003, Green left the band after suffering a nervous breakdown; official reports stated he was leaving to work with his side project, Vells. The same year, he and Judy appeared on Adam Forkner's first solo album, VVRSSNN. Drummer Benjamin Weikel joined the band, replacing Green, along with Murder City Devils guitarist Dann Gallucci, who had previously played with Modest Mouse. Prior to starting the band's writing and recording process, Brock was devastated by the loss of "a couple of the most important people in my life," he said. Following these events, the band released their fourth album, Good News for People Who Love Bad News, on April 6, 2004. The following August, the album was certified Platinum, having two hits with "Float On" and "Ocean Breathes Salty" (both of which they performed on Saturday Night Live on November 13, 2004). The album was nominated for a Grammy Award for Best Alternative Music Album that year, and "Float On" was nominated for Best Rock Song. Later that year, Green returned to the band and Weikel returned to drumming exclusively for the Helio Sequence.
