Duncan Lee Hunter (born May 31, 1948) is an American politician. He was a Republican member of the House of Representatives from California's 52nd, 45th and 42nd districts from 1981 to 2009. Hunter was the chairman of the House Armed Services Committee during the 108th and 109th Congress. Hunter sought the Republican Party nomination for President of the United States for 2008, but his campaign failed to attract significant voters or delegates in early primary and caucus states, and he dropped out after the Nevada Republican caucuses.
On December 8, 2006, Hunter introduced H.R. 6375, which would have required the defense department to post the purpose of all congressional earmarks in annual defense bills, along with the location and a grade according to the utility of the earmark.  Hunter introduced H.R. 552, The Right to Life Act, on February 2, 2005. The purpose of the bill is to "implement equal protection... for the right to life of each born and preborn human person." In the 109th Congress, the legislation collected 101 cosponsors. Hunter states that The Right to Life Act "would legally define "personhood" as the moment of conception and, therefore, guarantee all constitutional rights and protections, including life, to the unborn without utilizing a constitutional amendment." Hearings for H.R. 552 were scheduled for December 12, 2006, but were cancelled right before the House adjourned.  On April 28, 2004, Hunter introduced legislation that he said could "turn parents into prosecuting attorneys fighting a wave of obscenity." HR 6390 IH, also called the "Parents Empowerment Act", would allow the parent or guardian of a minor to sue in federal court anyone who knowingly disseminates material "that is harmful to minors", or specifically, "any pornographic communication, picture, image, graphic image file, article, recording, writing, or other pornographic matter of any kind", if it is distributed in a way that "a reasonable person can expect a substantial number of minors to be exposed to the material and the minor, as a result to exposure to the material, is likely to suffer personal or emotional injury or injury to mental or moral welfare."  In 1994, Hunter legislatively mandated the construction of 14 miles (23 km) of security fencing on the international land border separating San Diego County and Tijuana, Mexico. In 2005, Hunter introduced legislation calling for the construction of a reinforced fence along the entire U.S.-Mexico border, citing crime statistics as measures of San Diego-Tijuana fence's success. After successfully adding an amendment to a House-passed bill that ultimately stalled in House-Senate negotiations, Hunter's amendment was later incorporated into H.R. 6061, the Secure Fence Act, introduced by New York Congressman Peter T. King. He has said that if he becomes President, the 754-mile (1,213 km) double layer border fence will be built in less than 12 months.  Hunter repeatedly voted against international trade agreements such as the North American Free Trade Agreement (NAFTA), the Central America Free Trade Agreement (CAFTA) and the World Trade Organization (WTO).

A boy band (or boyband) is loosely defined as a vocal group consisting of young male singers, usually in their teenage years or in their twenties at the time of formation, singing love songs marketed towards young women. Being vocal groups, most boy band members do not play musical instruments, either in recording sessions or on stage, making the term something of a misnomer. However, exceptions do exist. Many boy bands dance as well as sing, usually giving highly choreographed performances.
The earliest forerunner of boy band music began in the late 19th century as a cappella barbershop quartets. They were usually a group of males and sang in four-part harmonies. Barbershop quartets were popular into the earlier part of the 20th century. A revival of the male vocal group took place in the late 1940s and 1950s with the use of doo-wop music. Doo-wop bands sang about topics such as love and other themes used in pop music. The earliest traces of boy bands were in the mid-1950s although the term boy band was not used. African American vocal group The Ink Spots was one of the first of what would now be called boy bands. The term boy band was not established until the late 1980s as before that they were called male vocal groups or "hep harmony singing groups".  Although generally described as a rock band, the highest-selling band in history The Beatles are considered by a number or journalists "the first" or "the original" boyband, "before anyone had thought of the term."  The Liverpool quartet known as The Beatles were not only the quintessential rock band, but many considered John Lennon, Paul McCartney, George Harrison and Ringo Star to be the original boy band -- especially in the early 1960s when young girls would scream at the top of their lungs and pass out upon first sight of the "Fab Four.  The Beatles inspired the decision to produce the 1966 television series The Monkees, which spawned the music group of the same name, formed by the four starring actors. The rock and pop band started a career in music after their songs from the TV series released as records resulted successful.

How did the boy band evolve over the years?
Barbershop quartets were popular into the earlier part of the 20th century.
