Andy Duncan (born 31 July 1962) is CEO of Camelot UK Lotteries Limited (Camelot Group), the operator of the UK National Lottery.
 Duncan started his career at Unilever – where he spent 17 years in a variety of senior managerial roles – before he was appointed director of Marketing, Communications and Audiences at the BBC.
 Duncan then became chief executive of Britain's Channel 4 television channel from July 2004 to November 2009 – the first not to have a background in programme making – and was the founding chairman of Freeview.
 After a year as CEO of H.R. Owen plc, the UK's leading luxury car business, he became UK managing director of Camelot in October 2011 and was subsequently appointed UK CEO in October 2014.

 It was released 30 August 2005.

Linx was a British soul/funk band consisting of David Grant (lead vocals), Bob Carter (keyboards), Andy Duncan (drums), Canute Edwards (guitar), Peter Martin (bass) (aka Sketch) and Junior Giscombe (backing vocals).
 After its first hit in 1980, the band slimmed down to a duo of Grant and Martin.
 They had six entries on the UK Singles Chart from mid 1980 until mid 1982.
 The band's biggest success was "Intuition," which reached number 7 in early 1981.
 Other hits included "You're Lying" and "So This is Romance."

Camelot Group are the operators of the UK National Lottery.
 Camelot Group was awarded the National Lottery franchise in May 1994 (though the lottery did not start until November 1994) and was re-awarded the franchise in 2001 and again in 2007.
 The current franchise period started in 2009 and runs until 2019, with a possible extension of up to five years.
 The governmental body the National Lottery Commission is responsible for deciding who is awarded the franchise.
 The way the franchise was awarded to Camelot in 2001 caused some controversy because state owned Royal Mail held a 20% stake in the Camelot Group.
Keys of the Kingdom is the fourteenth album by the rock band The Moody Blues, released in 1991.
 Although some of the tracks recall the songwriting on "Sur la Mer", the failure of "Keys of the Kingdom" to produce any major hit singles would mark the beginning of the Moodies' decline in popularity with mainstream audiences after their success in the MTV video generation.
 The album saw the band beginning to return to a more airy rock orientated sound (similar to "The Present"), rather than the previous two albums' forays into synthesiser pop.
 Flautist Ray Thomas plays more of a substantial role on this record, with his first ambient flute piece in eight years.
 The album was recorded and mixed at four London studios: Olympic Studios, RG Jones Studios, Mayfair Studios and The Hit Factory (not to be confused with the NYC-based studio of the same name).
 Drum machines are still used heavily; Graeme Edge only performs on three songs, with session drummer Andy Duncan providing live drums on two more, and the rest being programmed.
 Keyboardist Patrick Moraz was fired from the band after completing only a few tracks for this album, and he is listed as an 'additional' keyboard player.
 After a lawsuit on Court TV filed by Moraz, their future album and re-release booklets would distance themselves from Moraz - e.g. removing him from photographs that originally featured him - and they never had any future keyboardists become official members of the band.
