Background: Sparks are an American pop and rock band formed in Los Angeles in 1972 by brothers Ron (keyboards) and Russell Mael (vocals). The duo formed in 1968 under the name Halfnelson. Known for their quirky approach to songwriting, Sparks' music is often accompanied by intelligent, sophisticated, and acerbic lyrics, and an idiosyncratic, theatrical stage presence, typified in the contrast between Russell's animated, hyperactive frontman antics and Ron's deadpan scowling. They are also noted for Russell Mael's distinctive falsetto voice and Ron Mael's intricate and rhythmic keyboard playing style.
Context: Relocating to England in 1973 with a new manager, John Hewlett, founder of John's Children, and a deal from Island Records, thanks in part to the exposure garnered by their BBC Two Whistle Test performance, they placed an ad in music weekly Melody Maker ("Wanted bass player for Sparks. Must be beard free and exciting") and through this hired Martin Gordon. With Adrian Fisher on guitar and Norman "Dinky" Diamond on drums, in the midst of power cuts and a threatened vinyl shortage, they recorded their breakthrough Kimono My House in 1974, scoring a No. 2 hit with the single "This Town Ain't Big Enough for Both of Us", despite Elton John betting producer Muff Winwood that the song would not break into the charts. Sparks became a UK teen sensation appearing on the cover of Melody Maker, Record Mirror and countless other pop magazines in the UK and Europe. Hits such as "This Town Ain't Big Enough for Both of Us", "Amateur Hour" and "Never Turn Your Back on Mother Earth" led to many appearances on the BBC's flagship music show Top of the Pops. Russell's hyperactive movements were in sharp contrast to the keyboard-bound, soberly dressed Ron's expressionless squint and Charlie Chaplin-esque moustache. Gordon and Fisher were later replaced by Trevor White and Ian Hampton. In 1975, the revised band returned to the US to tour supporting the Kimono and Propaganda albums which had gained strong cult attention in New York City, Cleveland, Chicago, San Francisco and Los Angeles primarily from FM radio play and a national TV appearance on Don Kirshner's Rock Concert. Flo & Eddie were the supporting act. Influential 1970s progressive FM radio station powerhouse WMMS in Cleveland and its famed DJs such as Kid Leo initially championed the band in America. Sparks also performed on American Bandstand in 1975 with host Dick Clark mugging with Ron and on countless other TV shows in the US and abroad post 1977. The follow-up albums, Propaganda and Indiscreet, the latter produced by Tony Visconti, were similarly successful and produced the hit singles "Looks, Looks, Looks", "Never Turn Your Back on Mother Earth" and "Something for the Girl with Everything".
Question: Did they go on tour with the release of Kimono My House?
Answer: Gordon and Fisher were later replaced by Trevor White and Ian Hampton. In 1975, the revised band returned to the US to tour

Background: Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house that was built by his father. His parents were Hannah (Milhous) Nixon and Francis A. Nixon. His mother was a Quaker, and his father converted from Methodism to the Quaker faith. Nixon was a descendant of the early American settler, Thomas Cornell, who was also an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates.
Context: Nixon used the improving international environment to address the topic of nuclear peace. Following the announcement of his visit to China, the Nixon administration concluded negotiations for him to visit the Soviet Union. The President and First Lady arrived in Moscow on May 22, 1972 and met with Leonid Brezhnev, the General Secretary of the Communist Party; Alexei Kosygin, the Chairman of the Council of Ministers; and Nikolai Podgorny, the head of state, among other leading Soviet officials. Nixon engaged in intense negotiations with Brezhnev. Out of the summit came agreements for increased trade and two landmark arms control treaties: SALT I, the first comprehensive limitation pact signed by the two superpowers, and the Anti-Ballistic Missile Treaty, which banned the development of systems designed to intercept incoming missiles. Nixon and Brezhnev proclaimed a new era of "peaceful coexistence". A banquet was held that evening at the Kremlin. Seeking to foster better relations with the United States, both China and the Soviet Union cut back on their diplomatic support for North Vietnam and advised Hanoi to come to terms militarily. Nixon later described his strategy: I had long believed that an indispensable element of any successful peace initiative in Vietnam was to enlist, if possible, the help of the Soviets and the Chinese. Though rapprochement with China and detente with the Soviet Union were ends in themselves, I also considered them possible means to hasten the end of the war. At worst, Hanoi was bound to feel less confident if Washington was dealing with Moscow and Beijing. At best, if the two major Communist powers decided that they had bigger fish to fry, Hanoi would be pressured into negotiating a settlement we could accept. Having made considerable progress over the previous two years in U.S.-Soviet relations, Nixon embarked on a second trip to the Soviet Union in 1974. He arrived in Moscow on June 27 to a welcome ceremony, cheering crowds, and a state dinner at the Grand Kremlin Palace that evening. Nixon and Brezhnev met in Yalta, where they discussed a proposed mutual defense pact, detente, and MIRVs. While he considered proposing a comprehensive test-ban treaty, Nixon felt he would not have time as president to complete it. There were no significant breakthroughs in these negotiations.

Nixon used the improving international environment to address the topic of nuclear peace.
