Passage: The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.

Passage: In 1991, Makharadze's role was to manage the relations between the federal government and the various regional administrations of Russia, as a member of Boris Yeltsin's team. He was also involved in removing former Communist officials for suspected corruption as the Yeltsin administration's chief inspector, including what was referred to as "nomenklatura privatization." In March 1992 he was appointed as one of the Deputy Prime Ministers in Yeltsin's cabinet, being in charge of managing relations between the regions and the government in Moscow. As part of this, Makharadze and nationality minister Valery Tishkov signed an agreement with the German government to help resettle Volga Germans in their native region. Among his other tasks was to oversee the implementation of economic reforms begun by the central government in the regions. However, when Boris Yeltsin was making concessions to conservative opposition factions in order to gain approval for his economic privatization policies, despite the resignation of Deputy Prime Minister Mikhail Poltoranin it was expected the Makharadze would be forced to resign too. He suggested during this time that a stronger presidential administration was needed. Makharadze was removed from the position of deputy prime minister in December 1992, upon the formation of the new cabinet.

Passage: In June 1997, Spears was in talks with manager Lou Pearlman to join female pop group Innosense. Lynne asked family friend and entertainment lawyer Larry Rudolph for his opinion and submitted a tape of Spears singing over a Whitney Houston karaoke song along with some pictures. Rudolph decided to pitch her to record labels, which required a professional demo. He sent Spears an unused song from Toni Braxton; she rehearsed for a week and recorded in a studio with a sound engineer. Spears traveled to New York with the demo and met executives from four labels, returning to Kentwood the same day. Three rejected her, arguing audiences wanted pop bands such as the Backstreet Boys and the Spice Girls, and "there wasn't going to be another Madonna, another Debbie Gibson or another Tiffany." Two weeks later, executives from Jive Records returned calls to Rudolph. Senior vice president of A&R Jeff Fenster stated, "It's very rare to hear someone that age who can deliver emotional content and commercial appeal. [...] For any artist, the motivationthe 'eye of the tiger' is extremely important. And Britney had that." They appointed her to work with producer Eric Foster White for a month, who reportedly shaped her voice from "lower and less poppy" delivery to "distinctively, unmistakably Britney." Spears recorded thirteen songs with White, including "Autumn Goodbye", "E-Mail My Heart", "From the Bottom of My Broken Heart", "I'm So Curious", "I Will Still Love You", "Luv The Hurt Away", "Let Me Take You There", "Soda Pop", "Thinkin' About You", "Nothing Less Than Real", "Wishing on a Falling Star" and "You Got It All". The singer also recorded a cover of Sonny & Cher's 1967 single "The Beat Goes On". White was responsible for the vocal recording and song production, while additional production was done by English electronic music group All Seeing I.
