London ⁱ/ˈlʌndən/ is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom, and the largest urban zone in the European Union by most measures. Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the London region and the Greater London administrative area, governed by the elected Mayor of London and the London Assembly.

London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence. It is the world's leading financial centre alongside New York City and has the fifth-largest city GDP in the world (and the largest in Europe). London has been described as a world cultural capital. It was the world's most visited city during 2011 and London Heathrow is the world's busiest airport by number of international passengers. London's 43 universities form the largest concentration of higher education in Europe. In 2012 London will become the first city to host the modern Summer Olympic Games three times.

Polly Jean Harvey (born 9 October 1969) is an English musician, singer-songwriter, composer and occasional artist. Primarily known as a vocalist and guitarist, she is also proficient with a wide range of instruments including piano, organ, bass, saxophone, harmonica, and most recently, the autoharp.

Harvey began her career in 1988 when she joined local band Automatic Dlamini, whose vocalist and saxophone player, John Parish, would become her long-term collaborator. In 1991, she formed an eponymous trio and subsequently began her professional career. The trio released two studio albums, Dry (1992) and Rid of Me (1993) before disbanding, after which Harvey continued as a solo artist. Since 1995, she has released a further six studio albums with collaborations from various musicians including John Parish, former bandmate Rob Ellis, Mick Harvey, and Eric Drew Feldman and has also worked extensively with record producer Flood.

Among the accolades she has received are the 2001 and 2011 Mercury Prize for Stories from the City, Stories from the Sea (2000) and Let England Shake (2011) respectively—the only artist to have been awarded the prize twice—eight BRIT Award nominations, six Grammy Award nominations and two further Mercury Prize nominations. Rolling Stone awarded her 1992's Best New Artist and Best Singer Songwriter and 1995's Artist of the Year, and listed Rid of Me and To Bring You My Love (1995) on its 500 Greatest Albums of All Time list. In 2011, she was awarded for Outstanding Contribution To Music at the NME Awards.

Kelly Brianne Clarkson (born April 24, 1982) is an American singer, songwriter and occasional actress. Clarkson came into prominence after becoming the winner of the inaugural season of the television series American Idol in 2002 and later was the runner-up in the television special World Idol in 2003.

In 2003, Clarkson released her debut album, Thankful, which was a commercial success and established herself in the pop music industry. The release of its first single, "A Moment Like This" (2002), broke The Beatles' record for the biggest leap to number one, from 52, in the history of the Billboard Hot 100 chart. After parting ways with her management, Clarkson developed a more rock-oriented music with the release of her critically acclaimed sophomore album, Breakaway (2004), which sold more than 12 million copies worldwide and which garnered Clarkson more worldwide success as a pop rock artist. The album's single, "Because of You" (2005), became the best-selling single by an Idol contestant worldwide. In 2007, Clarkson took full creative control for her third album My December, which had a more rock-inspired sound and was met with controversy and moderate success. Clarkson later returned to a more pop-oriented sound with All I Ever Wanted (2009), which became a commercial and critical success. The album's lead single, "My Life Would Suck Without You" (2009), surpassed "A Moment Like This"'s record for the biggest leap to number one on a single week in the history of the Billboard Hot 100 Chart, a milestone it still holds today. Furthermore, it also became her first number one single in the United Kingdom. Clarkson's fifth studio album, Stronger, was released in 2011, containing elements from synthpop, R&B and country music. The album's single, "Stronger (What Doesn't Kill You)" (2012), became her longest number one single and eventually became her best-selling single in the United States.
