Pete and Dud: Come Again is a stage play about British "Beyond the Fringe" comedians Peter Cook and Dudley Moore, which was written by Chris Bartlett and Nick Awde.
 The comedy-drama had a sellout run at the Assembly Rooms as part of the 2005 Edinburgh Festival Fringe, where it was shortlisted for a Fringe First Award by The Scotsman, before moving to London's West End at The Venue in March 2006; this version starred Kevin Bishop as Moore, Tom Goodman-Hill as Cook, Colin Hoult as Jonathan Miller and Fergus Craig as Alan Bennett.
 It was published in playtext form by Methuen.
Cox performed his first major show – entitled "Chris Cox He Can Read Minds?"
 – at the 2006 Edinburgh Festival Fringe.
 Cox's second show, "Everything Happens for a Reason" ran at the Gilded Balloon during the 2007 Fringe before a one off performance at the Arts Theatre in London's West End.
 His show "Chris Cox : Control Freak" premiered at the 2008 Edinburgh Festival Fringe at the Pleasance after which it had a UK Tour and finished with a performance at the Southbank Centre in London.
 He also performed with Frank Skinner, Jonathan Ross, Tim Minchin and featured on the television programmes The Culture Show and The Mentalist Revealed.
The 1948 Edinburgh Festival Fringe was the second edition of what would become the world's largest arts festival, the Edinburgh Festival Fringe.
 It was in this year the word "Fringe" is commonly accepted as having first been associated with the event, after it was used by an Edinburgh Evening News critic.
 The term would come to define the event, and spawn the genre of fringe theatre.
 It was, however, still several years before it became common parlance in connection with the event or theatre in general, and also some time before any formal organisation of the event took place.
The 2003 Edinburgh Festival Fringe was the 56th Edinburgh Festival Fringe.
 The Fringe ran from 3–25 August 2003 and presented 1541 shows over 207 venues.
 2003 was the first year that over one million tickets were sold at the Fringe.
The Edge Festival was an annual music festival held in Edinburgh, Scotland, during August of each year.
 Formerly known as T on the Fringe, The Edge was part of the Edinburgh Festival Fringe, the world's largest arts fringe festival (to the larger Edinburgh Festival).
 Unlike other music festivals, The Edge did not take place at one location, with performers instead playing numerous venues across the city during the month.
 The festival was founded under the T on the Fringe name by DF Concerts and Tennent's Lager, with DF continuing to promote the festival after the departure of Tennent's from 2008 until 2012.
The Edinburgh Festival Fringe Society is the organisation that supports the running of the Edinburgh Festival Fringe, the largest arts festival in the world.
 The Society was established in 1958 to provide a centralised information and box office service for the Fringe, which had grown in numbers since eight theatre companies had effectively "created" the Fringe by performing uninvited alongside the Edinburgh International Festival in 1947.
A Trip to the Moon is a 1964 television science fiction comedy film, produced as an episode of the CBS series "Chronicle".
 The script was written by Jonathan Miller and Robert Goldman, based on Jules Verne's novel "From the Earth to the Moon".
 All characters are portrayed by Alan Bennett, Peter Cook, Miller, and Dudley Moore, who had first worked together in the revue "Beyond the Fringe".
Alan Bennett (born 9 May 1934) is a British playwright, screenwriter, actor and author.
 He was born in Leeds and attended Oxford University where he studied history and performed with the Oxford Revue.
 He stayed to teach and research medieval history at the university for several years.
 His collaboration as writer and performer with Dudley Moore, Jonathan Miller and Peter Cook in the satirical revue "Beyond the Fringe" at the 1960 Edinburgh Festival brought him instant fame.
 He gave up academia, and turned to writing full-time, his first stage play "Forty Years On" being produced in 1968.
Beyond the Fringe was a British comedy stage revue written and performed by Peter Cook, Dudley Moore, Alan Bennett, and Jonathan Miller.
 It played in London's West End and then in America, both on tour and on New York's Broadway in the early 1960s.
 Hugely successful, it is widely regarded as seminal to the rise of satirical comedy in 1960s Britain.
Sir Jonathan Wolfe Miller, CBE (born 21 July 1934) is an English theatre and opera director, actor, author, television presenter, humourist, and medical doctor.
 While training in medicine, and specialising in neurology, in the late 1950s, he first came to prominence in the early 1960s with his role in the comedy revue "Beyond the Fringe" with fellow writers and performers Peter Cook, Dudley Moore and Alan Bennett.
