Question: Focus are a Dutch rock band formed in Amsterdam in 1969 by keyboardist, vocalist, and flautist Thijs van Leer. The band have undergone numerous formations in its history; since December 2016 it has comprised van Leer, drummer Pierre van der Linden, guitarist Menno Gootjes, and bassist Udo Pannekeet. Past members include guitarist Jan Akkerman and bassist Bert Ruiter. They have sold one million RIAA-certified albums in the United States.

Focus formed in mid-1969 by keyboardist, vocalist, and flautist Thijs van Leer, who recruited bass guitarist Martijn Dresden and drummer Hans Cleuver after he met them at sessions for the Jazz and Poetry radio program in Hilversum, Netherlands. The three went on to start a new three-piece band initially known as Thijs van Leer and the Rebaptised, playing a set formed mostly of cover songs by Traffic and original material mostly written by van Leer. In November 1969, during rehearsals at the theatre where van Leer performed as part of Ramses Shaffy's theatre group, they were joined by guitarist Jan Akkerman of the rock band Brainbox after Shaffy invited him to play with the trio. Van Leer later recalled the first try out session: "Jan came in and we jammed for hours, and it was really kicking". They then settled on the name Focus for the new band; Akkerman later said, "Focus is a Latin word that is the same in many languages. It means concentration, which is the meaning of what Focus does". Their first live gig as Focus followed at the Bird's Club in Rembrandtplein, and they soon secured a weekly residency playing two shows a night on two days. Early sets were mainly formed of covers, including "I Shall Be Released" by Bob Dylan, "A Whiter Shade of Pale" by Procol Harum and "Nights in White Satin" by The Moody Blues, mixed with original material, including van Leer's first song written with the group in mind, the instrumental "Focus". In their search for more work and a steady income, Focus was chosen to play as part of the pit band for the Dutch production of the rock musical Hair produced by Welsh actor Victor Spinetti. They were invited to audition at the Victoria Ballroom, London after Dutch lyricist Lennaert Nijgh suggested them to Del Newman, the musical's director. Cast member Robin Lent claimed the production was suffering and Focus, taking part only for the money, "were also pretty rusty ... but this changed and everybody got into it". The show, launched in December 1969, involved six nightly performances a week and gave them space to rehearse in the afternoons for free and store their equipment. An album of the soundtrack featuring the band was recorded in February 1970 and released soon after by Polydor Records. After Hair ended its run in June 1970, Focus declined an offer to tour the musical across the Netherlands for a year and a half and become a full time band. They had picked up more local gigs and dates across the country by this time, and had performed their first international gigs in Belgium and Spain. Their weekly earnings from gigs, plus their earnings from Hair, had reached 400 guilders though Akkerman recalled the group failed to appreciate its value and were quick to spend it. To manage their finances more carefully, Cleuver was chosen to oversee their earnings and expenses.

Question: Daniel Irvin Rather, Jr. was born on October 31, 1931, in Wharton County, Texas, the son of Daniel Irvin Rather, Sr., a ditch digger, and the former Byrl Veda Page. The Rathers moved to Houston, where Dan attended Love Elementary School and Hamilton Middle School. He graduated in 1950 from John H. Reagan High School in Houston. In 1953, he earned a bachelor's degree in journalism from Sam Houston State University where he was editor of the school newspaper, The Houstonian.

On October 4, 1986, while walking along Park Avenue to his apartment in Manhattan, Rather was attacked and punched from behind by a man who demanded to know "Kenneth, what is the frequency?" while a second assailant chased and beat him. As the assailant pummeled and kicked Rather, he kept repeating the question. In describing the incident, Rather said, "I got mugged. Who understands these things? I didn't and I don't now. I didn't make a lot of it at the time and I don't now. I wish I knew who did it and why, but I have no idea." Until the crime was resolved years later, Rather's description of the bizarre crime led some to doubt the veracity of his account, although the doorman and building supervisor who rescued Rather fully confirmed his version of events. The assault remained unsolved for some time, and was referenced multiple times in popular culture. The phrase "What's the frequency, Kenneth?" became a popular-culture reference over the years, such as in a scene in the graphic novel Like a Velvet Glove Cast in Iron by cartoonist Daniel Clowes. In 1994, the band R.E.M. released the song "What's the Frequency, Kenneth?" on their album Monster. Rather later sang with R.E.M. during a sound check prior to a gig at New York's Madison Square Garden, which was shown the following night on the Late Show with David Letterman before their performance of "Crush with Eyeliner". In 1997, a TV critic writing in the New York Daily News solved the mystery, publishing a photo of the alleged assailant, William Tager, who received a 12 1/2 -to-25-year prison sentence for killing NBC stagehand Campbell Montgomery outside The Today Show studio in 1994. Rather confirmed the story: "There's no doubt in my mind that this is the person." New York District Attorney Robert M. Morgenthau said, "William Tager's identity as the man who attacked Mr. Rather was established in the course of an investigation by my office." Tager claimed he thought television networks were beaming signals into his brain. When he murdered the stagehand, Tager was trying to force his way into an NBC studio with a weapon, in order to find out the frequency the networks were using to attack him, so that he could block it. Tager was paroled in October 2010 and is believed to be living in New York City.
