Answer the question at the end by quoting:

Yes are an English progressive rock band formed in London in 1968 by singer Jon Anderson, bassist Chris Squire, guitarist Peter Banks, keyboardist Tony Kaye, and drummer Bill Bruford. The band have undergone numerous formations throughout their history; nineteen musicians have been full-time members. Since June 2015, it has consisted of guitarist Steve Howe, drummer Alan White, keyboardist Geoff Downes, singer Jon Davison, and bassist Billy Sherwood, with no remaining founding members. Yes have explored several musical styles over the years, and are most notably regarded as progressive rock pioneers.
In 1980, pop duo the Buggles (keyboardist Geoff Downes and singer Trevor Horn) acquired Brian Lane as a manager.  At this point, the departure of Anderson and Wakeman had been kept secret from everyone outside the Yes inner circle. Seeing an option of continuing the band with new creative input and expertise, Squire revealed the situation to Horn and Downes and suggested that they join Yes as full-time members. Horn and Downes accepted the invitation and the reconfigured band recorded the Drama album, which was released in August 1980. The record displayed a heavier, harder sound than the material Yes recorded with Anderson in 1979, opening with the lengthy hard rocker "Machine Messiah". The album received substantial radio airplay in the late summer-fall of 1980, and peaked at number 2 in the UK and number 18 in the US, though it was the first Yes album to not be certified Gold by the RIAA since 1971. Their 1980 tour of North America and the UK received a mixed reaction from audiences. They were well received in the United States, and were awarded with a commemorative certificate after they performed a record 16 consecutive sold out concerts at Madison Square Garden since 1974.  After the Drama tour, Yes reconvened in England to decide the band's next step, beginning by dismissing Lane as their manager. Horn chose to leave Yes to pursue a career in music production, with White and Squire next to depart. Left as the sole remaining members, Downes and Howe opted not to continue with the group and went their own separate ways in December 1980. A live compilation album of Yes performances from 1976 to 1978, mixed in mid-1979 and originally intended for release in late 1979, was released as Yesshows, peaking at number 22 in the UK charts and number 43 in the US. An announcement came from the group's management in March 1981 confirming that Yes no longer existed.  Downes and Howe later reunited to form Asia with former King Crimson bassist and vocalist John Wetton, and drummer Carl Palmer from Emerson, Lake, and Palmer. Squire and White continued to work together, initially recording sessions with Jimmy Page for a proposed band called XYZ (short for "ex-Yes-and-Zeppelin") in the spring of 1981. Page's former bandmate Robert Plant was also to be involved as the vocalist but he lost enthusiasm, citing his ongoing grieving for recently deceased Led Zeppelin drummer John Bonham. The short-lived group produced a few demo tracks, elements of which would appear in Page's band the Firm and on future Yes tracks "Mind Drive" and "Can You Imagine?". In late 1981, Squire and White released "Run with the Fox", a Christmas single with Squire on vocals which received radio airplay through the 1980s and early 1990s during the Christmas periods. A second Yes compilation album, Classic Yes, was released in November 1981.

What happened in 1980?

Downes and Howe opted not to continue with the group and went their own separate ways in December 1980.

IN: Canby was born in Piatt's Landing, Kentucky, to Israel T. and Elizabeth (Piatt) Canby. He attended Wabash College, but transferred to the United States Military Academy, from which he graduated in 1839. He was commissioned a second lieutenant in the 2nd U.S. Infantry and served as the regimental adjutant. Although often referred to as Edward Canby, a biographer has suggested that he was known as "Richard" during childhood and to some friends for most of his life.

During his early career, Canby served in the Second Seminole War in Florida and saw combat during the Mexican-American War, where he received three brevet promotions, including to major for Contreras and Churubusco, and lieutenant colonel for Belen Gates. He also served at various posts, including Upstate New York and in the adjutant general's office in California from 1849 until 1851, covering the period of the territory's transition to statehood.  Against his wishes, he was assigned to what was supposed to be the civilian post of custodian of the California Archives from March 1850 until he left California in April 1851. The Archives included records of Spanish and Mexican governments in California, as well as Mission records and land titles. Evidently, Canby had some knowledge of the Spanish language, which was extremely useful as the government was trying to unravel land titles. (The Filson Historical Society in Louisville, Kentucky holds what appears to be a document written in Canby's hand in Spanish, in which he identifies himself as "Edwardo  [sic] Ricardo S. Canby.")  Canby served in Wyoming and Utah (then both part of the Utah Territory) during the Utah War (1857-1858). During this period, he served on the panel of judges for the court martial of Captain Henry Hopkins Sibley. Sibley was acquitted. Subsequently, Canby wrote an endorsement for a teepee-like army tent which Sibley had adapted from the American Indian style.  Both officers were later assigned to New Mexico, where in 1860 Canby coordinated a campaign against the Navajo, commanding Sibley in a futile attempt to capture and punish Navajo for "depredations" against the livestock of settlers. The campaign ended in frustration, with Canby and Sibley rarely sighting Navajo raiders. Usually they saw the Navajo at a distance and never got close to them.
