Answer the question at the end by quoting:

The Royal Philharmonic Orchestra (RPO), based in London, was formed by Sir Thomas Beecham in 1946. In its early days the orchestra secured profitable recording contracts and important engagements including the Glyndebourne Festival Opera and the concerts of the Royal Philharmonic Society. After Beecham's death in 1961 the orchestra's fortunes declined steeply; it battled for survival until the mid-1960s, when its future was secured after an Arts Council report recommended that it should receive public subsidy; a further crisis arose in the same era when it seemed that the orchestra's right to call itself "Royal" could be withdrawn. Since Beecham's death the RPO has had seven chief conductors, including Rudolf Kempe, Antal Dorati, Andre Previn and Vladimir Ashkenazy, and most recently Charles Dutoit.
In 1932 the conductor Sir Thomas Beecham had founded the London Philharmonic Orchestra (LPO), which, with the backing of rich supporters, he ran until 1940, when finances dried up in wartime. Beecham left to conduct in Australia and then the US; the orchestra continued without him after reorganising itself as a self-governing body. On Beecham's return to England in September 1944 the LPO welcomed him back, and in October they gave a concert together that drew superlatives from the critics. Over the next months Beecham and the orchestra gave further concerts with considerable success, but the LPO players, now their own employers, declined to give him the unfettered control he had exercised in the 1930s. If he were to become chief conductor again it would be as a paid employee of the orchestra. Beecham responded, "I emphatically refuse to be wagged by any orchestra ... I am going to found one more great orchestra to round off my career." In 1945 he conducted the first concert of Walter Legge's new Philharmonia Orchestra, but was not disposed to accept a salaried position from Legge, his former assistant, any more than from his former players in the LPO. His new orchestra to rival the Philharmonia would, he told Legge, be launched in "the most auspicious circumstances and eclat". In 1946 Beecham reached an agreement with the Royal Philharmonic Society: his new orchestra would replace the LPO at all the Society's concerts. He thus gained the right to name the new ensemble the "Royal Philharmonic Orchestra", an arrangement approved by George VI. Beecham arranged with the Glyndebourne Festival that the RPO should be the resident orchestra at Glyndebourne seasons. He secured backing, including that of record companies in the US as well as Britain, with whom lucrative recording contracts were negotiated. The music critic Lyndon Jenkins writes: Naturally, it quickly became known that he was planning another orchestra, at which the cry "He'll never get the players!" went up just as it had done in 1932. Beecham was unmoved: "I always get the players," he retorted. "Among other considerations, they are so good they refuse to play under anybody but me".

Why did he leave?

finances dried up in wartime.

Some context: Burton was born to American parents at the U.S. Army Landstuhl Regional Medical Center in West Germany. His mother, Erma Gene (nee Christian), was a social worker, administrator, and educator. His father, Levardis Robert Martyn Burton, was a photographer for the U.S. Army Signal Corps at the time he was stationed at Landstuhl. Burton and his two sisters were raised by his mother in Sacramento, California.
Burton first appeared on television in a drama about a misunderstood deaf boy. LeVar Burton made his film acting debut in 1977 when he played Kunta Kinte in the ABC award-winning drama series Roots, based on the novel by Alex Haley. Burton's audition for the role of Kinte was the first of his professional career. As a result of his performance, he was nominated for the Emmy for Best Actor in a Drama Series. Burton reprised the role of Kunta Kinte in the 1988 television film Roots: The Gift. When asked about the societal impacts of Roots, Burton is quoted as saying, "It expanded the consciousness of people. Blacks and whites began to see each other as human beings, not as stereotypes. And if you throw a pebble into the pond, you're going to get ripples. I think the only constant is change, and it's always slow. Anything that happens overnight is lacking in foundation. Roots is part of a changing trend, and it's still being played out." Burton played a role as a visitor to Fantasy Island, was a participant in Battle of the Network Stars, a guest of the Muppet Show's televised premiere party for the release of The Muppet Movie, and a frequent guest on several game shows. In 1986, he appeared in the music video for the song "Word Up!" by the funk/R&B group Cameo. Burton accepted an invitation to host Rebop, a multicultural series designed for young people ages 9-15, produced by WGBH for PBS.

IN: Xenomania is an English songwriting and production team founded by Brian Higgins and based in Kent, England. Formed after Higgins met Miranda Cooper, Xenomania has written and produced for renowned artists such as Cher, Kylie Minogue, Dannii Minogue, Sophie Ellis-Bextor, Pet Shop Boys, The Saturdays and the Sugababes. In particular, all but one of Girls Aloud's studio albums have been entirely written and produced by Xenomania. Sugababes' "Round Round" and Girls Aloud's "Sound of the Underground" have been credited with reshaping British pop music for the 2000s.

Xenomania worked with American pop singer Britney Spears in 2003 during sessions for her fourth album In the Zone. The song submitted, "Graffiti My Soul", was not chosen for the album. While the record company loved the song, Spears felt that it needed more of a chorus. Higgins said that they wanted "essentially 'Sound of the Underground 2'." It later appeared on Girls Aloud's What Will the Neighbours Say?. The production team were due to work with rock bands New Order and Franz Ferdinand, but both sessions proved fruitless. Xenomania was due to produce for New Order's Waiting for the Sirens' Call, but Peter Hook said they "scrapped the Brian Higgins stuff because we didn't like it. I thought he did quite a good job on Girls Aloud but he didn't do a good job on us." Franz Ferdinand's drummer Paul Thomson said, "We wrote with Higgins for a while and initially we thought we'd work more with him but it didn't really work out. We just realized that we're not really a pop group." Xenomania were reported to have written five songs for Leona Lewis's second album, Echo (2009), described by Cooper as "tragic songs with a twist". The songs did not make the album. In 2012, Xenomania were reported to be working with Christina Aguilera. Higgins spoke of bad experiences with bigger artists to Literally magazine in 2009: "Everything about us is about enormous enthusiasm for something. And therefore big artists can come in and they think "they're the flavour of the whatever, let's take their thing and then we'll do what we want with it..." Well, no, that's not acceptable anyway. I've had that experience happen where the big artists were fine until they got into the mix room and then they basically pulled the record to pieces. So I took my name off the record and the writing credits off the record. Because they're assholes. And they sold about 20,000 copies, and they've never been seen since. So big artists are often jerks of the biggest order. And often people say don't meet your heroes because you'll be let down, and I sort of understand why people would say that."

Who said He didn't do a good job on us, New Order or Franz Ferdinand ?
