In April 1938, The Morris Brothers, fiddler Homer Sherrill and banjo player Joel Martin, calling themselves the Smilin' Rangers, performed at radio station WBTM in Danville, Virginia. In September 1938, Zeke recorded with Charlie Monroe as a replacement for Bill Monroe just after the Monroe Brothers had disbanded. The same year, Zeke's musical career came to a halt when he went to work in a cotton mill in Gastonia. In 1939, the brothers moved to Asheville and WWNC radio, where they resumed their career. After World War II they retired and opened an auto repair business. Between 1938 and 1939, the Morris Brothers made 36 recordings for RCA Victor.
 Passage 2:After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.

[EX Q]: Question: How many years passed between Jackson's first single and her last? Passage 1:The singles discography of Wanda Jackson, an American recording artist, consists of seventy-eight singles, nine international singles, one charting b-side, and three music videos. In 1954 at age sixteen, she signed as a country artist with Decca Records. Her debut single was a duet recording with Billy Gray which reached the eighth spot on the Billboard Hot Country Singles chart, also in 1954. Refusing to tour until completing high school, Jackson's further singles for Decca failed gaining success. She signed with Capitol Records in 1956 and began incorporating rock and roll into her musical style. Jackson's first Capitol single exemplified this format ("I Gotta Know") and became a national top-twenty country hit. Follow-up rock singles between 1957 and 1959 failed gaining enough attention to become hits including, "Hot Dog! That Made Him Mad", "Fujiyama Mama", and "Honey Bop". In 1960 however, the rock and roll-themed, "Let's Have a Party", became Jackson's first Billboard top-forty pop hit after it was picked up by an Iowa disc jockey.
 Passage 2:Whitman's poem appears in the Broadway musical Street Scene (1946) which was the collaboration of composer Kurt Weill, poet and lyricist Langston Hughes, and playwright Elmer Rice. Rice adapted his 1929 Pulitzer prize-winning play of the same name for the musical. In the play, which premiered in New York City in January 1947, the poem's third stanza is recited, followed by duet, "Don't Forget The Lilac Bush", inspired by Whitman's verse. Weill received the first Tony Award for Best Original Score for this work African-American composer George T. Walker, Jr. (born 1922) set Whitman's poem in his composition Lilacs for voice and orchestra which was awarded the 1996 Pulitzer Prize for Music. The work, described as "passionate, and very American," with "a beautiful and evocative lyrical quality" using Whitman's words, was premiered by the Boston Symphony Orchestra on February 1, 1996. Composer George Crumb (born 1929) set the Death Carol in his 1979 work Apparition (1979), an eight-part song cycle for soprano and amplified piano.
 Passage 3:At the 1989 election, Buchanan successfully transferred to the newly recreated seat of Ashburton, with her replacement in Pilbara, Larry Graham, retaining that seat for Labor. The re-elected Dowding government persisted only until February 1990, when it was replaced by the Lawrence government following Dowding's forced resignation. New premier Carmen Lawrence elevated Buchanan to the ministry as Minister for Works and Services and Minister for Regional Development. She was also made assistant minister to Lawrence in her capacity as Minister for Aboriginal Affairs. However, the regional development portfolio was abolished in December 1990, and Buchanan lost her remaining portfolios in February 1991, as part of a ministerial reshuffle prompted by an internal spill motion. Jeff Carr and Gavan Troy were also removed as ministers, with Carr consequently resigning from parliament. Buchanan herself resigned to sit as an independent on 1 February 1991, before the new ministry was sworn in four days later. She consequently became the first woman in the Parliament of Western Australia to sit as an independent. Buchanan resigned due to ill health just over a year later, in March 1992, and died at the end of that month, aged 55. She had married George Maitland Buchanan in April 1957, with whom she had two daughters. Her resignation prompted a by-election in Ashburton, which was won by the Labor candidate Fred Riebeling.

Passage 1:On March 8, 2017, it was announced that 20th Century Fox had bought the spec script Bad Times at the El Royale, written by Drew Goddard, who would also direct and produce the film.

 Passage 2:Southern Utah has the densest population of slot canyons in the world with over one thousand slot canyons in the desert lands south of Interstate 70. Utah's slot canyons are found in Zion National Park at The Narrows, along Canyonlands National Park's Joint Trail, throughout Capitol Reef National Park, within the San Rafael Swell and the Grand Staircase-Escalante National Monument, especially along the Escalante River drainage including Coyote Gulch. Many more slot canyons are located on public Bureau of Land Management and state-owned lands in southern Utah, in areas surrounding the aforementioned parks and monuments. Buckskin Gulch—one of the longest slot canyons in the world—begins in southern Utah and continues into northern Arizona within the Paria Canyon-Vermilion Cliffs Wilderness. Northern Arizona also has a high concentration of slot canyons including Antelope Canyon and Secret Canyon, which are two of the most famous slot canyons located near Page on land owned by the Navajo Nation. Slot canyons are also located in the valley between U.S. Route 89 and the Vermilion Cliffs in Arizona, and can be seen as one descends into the valley on U.S. 89, but these are on the Navajo reservation and are closed to the public. The Kasha-Katuwe Tent Rocks National Monument's slot canyon trail in New Mexico is unique as it was carved into tuff (volcanic ash). In California, several slot canyons are located within Death Valley National Park.
 Passage 3:The film was only a modest hit when first released. O'Connor won the Golden Globe Award for Best Actor – Motion Picture Musical or Comedy, and Betty Comden and Adolph Green won the Writers Guild of America Award for their screenplay, while Jean Hagen was nominated for the Academy Award for Best Supporting Actress. However, it has since been accorded legendary status by contemporary critics, and is frequently regarded as the best film musical ever made, and the best film ever made in the "Freed Unit" at Metro-Goldwyn-Mayer. It topped the AFI's Greatest Movie Musicals list and is ranked as the fifth-greatest American motion picture of all time in its updated list of the greatest American films in 2007. In 1989, the United States Library of Congress selected the film for preservation in the National Film Registry. In 2005 the British Film Institute included it in its list of the 50 films to be seen by the age of 14. In Sight & Sound magazine's 2017 list of the 50 greatest films of all time, Singin' in the Rain placed 20th.
