Background: The Mothers of Invention were an American rock band from California that served as the backing musicians for Frank Zappa. Formed in 1964, their work is marked by the use of sonic experimentation, innovative album art, and elaborate live shows. Originally an R&B band called the Soul Giants, the band's first lineup included Ray Collins, David Coronado, Ray Hunt, Roy Estrada and Jimmy Carl Black. Zappa was asked to take over as the guitarist following a fight between Collins and Coronado, the band's original saxophonist/leader.
Context: Later in 1970, Zappa formed a new version of the Mothers (from then on, he mostly dropped the "of Invention"). It included British drummer Aynsley Dunbar, jazz keyboardist George Duke, Ian Underwood, Jeff Simmons (bass, rhythm guitar), and three members of the Turtles: bass player Jim Pons, and singers Mark Volman and Howard Kaylan, who, due to persistent legal and contractual problems, adopted the stage name "The Phlorescent Leech and Eddie", or "Flo & Eddie". This version of the Mothers debuted on Zappa's next solo album Chunga's Revenge (1970), which was followed by the double-album soundtrack to the movie 200 Motels (1971), featuring the Mothers, the Royal Philharmonic Orchestra, Ringo Starr, Theodore Bikel, and Keith Moon. Co-directed by Zappa and Tony Palmer, it was filmed in a week at Pinewood Studios outside London. Tensions between Zappa and several cast and crew members arose before and during shooting. The film deals loosely with life on the road as a rock musician. It was the first feature film photographed on videotape and transferred to 35 mm film, a process which allowed for novel visual effects. It was released to mixed reviews. The score relied extensively on orchestral music, and Zappa's dissatisfaction with the classical music world intensified when a concert, scheduled at the Royal Albert Hall after filming, was canceled because a representative of the venue found some of the lyrics obscene. In 1975, he lost a lawsuit against the Royal Albert Hall for breach of contract. After 200 Motels, the band went on tour, which resulted in two live albums, Fillmore East - June 1971 and Just Another Band From L.A.; the latter included the 20-minute track "Billy the Mountain", Zappa's satire on rock opera set in Southern California. This track was representative of the band's theatrical performances in which songs were used to build up sketches based on 200 Motels scenes as well as new situations often portraying the band members' sexual encounters on the road.

Background: Sam Houston was the fifth son of Major Samuel Houston and Elizabeth Paxton. Houston's paternal ancestry is often traced to his great-great grandfather Sir John Houston, who built a family estate in Scotland in the late seventeenth century. His second son John Houston emigrated to Ulster, Ireland, during the Ulster plantation period. Under the system of primogeniture, he did not inherit the estate.
Context: Houston was twice elected President of the Republic of Texas. In the 1836 election, he defeated Stephen F. Austin and Henry Smith with a landslide of over 79% of the vote. Houston served from October 22, 1836, to December 10, 1838. The Constitution of the Republic of Texas stated that no president could succeed himself, but did not prohibit any non-consecutive multiple terms. When his first term ended, he was elected to serve as a representative from San Augustine County in the Republic of Texas House of Representatives. After his term as representative ended, Houston again served as President of the Republic of Texas from December 12, 1841, to December 9, 1844. While he initially sought annexation by the U.S., Houston dropped that goal during his first term. In his second term, he strove for fiscal prudence and worked to make peace with the various tribes of Native Americans in the Republic. He also struggled to avoid war with Mexico, whose forces invaded twice during 1842. In response to the Regulator-Moderator War of 1844, he sent in Republic militia to put down the feud. Houston still believed that the U.S annexation of Texas was not a realistic goal and the U.S. Senate would never pass it because of the delicate situation between the recently independent Texas and Mexico. However, Houston was a politician and as such he sought to preserve his career by endorsing the support of annexation into the U.S. Without his endorsement, the Texas congress would have put the question to public election and upon its likely passing would have effectively destroyed Houston's career as a Texas politician. To help save his political reputation, Houston sent James Pinckney Henderson to Washington to help Isaac Van Zandt advocate the annexation of Texas.
Question: What year did this begin?
Answer: Houston was twice elected President of the Republic of Texas. In the 1836 election,

Background: A marching band is a group in which instrumental musicians perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military style, that includes an associated school or organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags and rifles.
Context: Many bands have auxiliaries that add a visual component to the performance. For ceremonial bands, this could be a traditional color guard or honor guard. For drum & bugle corps and corps-style field bands, this could include Dance lines, majorettes, Auxiliary units may be collectively referred to as color guard or visual ensemble. Auxiliaries may perform as independent groups. In the early 1970s, color guards began to hold their own competitions in the winter (after the American football season, and before the beginning of the summer drum and bugle corps season). These became known as winter guard. There are also numerous dance competitions in the off-season. The color guard of a marching band or drum and bugle corps may contain sabers, mock rifles, and tall flags. In modern bands, other props are often used: flags of all sizes, horizontal banners, vertical banners, streamers, pom-poms, even tires, balls, and hula hoops or custom built props. The color guard may also employ stage dressing such as backdrops, portable flats, or other structures. These can be used simply as static scenery or moved to emphasize block drill, and are often used to create a "backstage" area to store equipment and hide personnel. While military color guards were typically male, band color guards tend to be primarily female, though it is becoming more common for men to join as well. A few independent units are all-male. Guard members nearly always wear a special uniform or costume that is distinctive from that of the band, not necessarily matching in design or color. The men's and women's guard uniforms are usually designed in one of two ways: nearly identically, but with gender-specific parts (i.e. skirts) adapted for the use of the opposite sex; or complimentarily, with the two uniforms designed similarly but with variations in color or form. The color guard uniform, especially in a high school marching band, need not be in school colors; in fact, they rarely are. These uniforms are designed to represent a certain aspect of the halftime show, characterize the guard members through costumes, or tell some sort of story, and can thus be in any design or color (a surprisingly common complaint among the high school audience is that guard uniforms and equipment "aren't school colors"). Indoor color guards have become popular within high schools and universities throughout the United States. These groups perform a theme-based show in competitions after the outdoor marching band season ends. Indoor color guard shows are typically performed in school gymnasiums and are adjudicated.
Question: Do they compete any other time of the year?
Answer:
after the American football season, and before the beginning of the summer drum and bugle corps season
