Daisy Johnson, also known as Quake, is a fictional superhero appearing in American comic books published by Marvel Comics.
 Created by writer Brian Michael Bendis and artist Gabriele Dell'Otto, the character first appeared in "Secret War" #2 (July 2004).
 The daughter of the supervillain Mister Hyde, she is a secret agent of the intelligence organization S.H.I.E.L.D. with the power to generate earthquakes.
 In the television series "Agents of S.H.I.E.L.D.", Chloe Bennet portrays the Marvel Cinematic Universe version of the character, where she is reimagined as an Inhuman originally known as Skye.
 Aspects of this interpretation were later integrated into the comics.
Alisdair Simpson (born 31 December 1969) is a British actor and narrator.
 Alongside his acting credits in theatre and television he has narrated over 200 documentaries including "", "Lost Land of the Jaguar", "Expedition Borneo", "Operation Iceberg", "Doctors in the Death Zone", "The Somme – From Defeat to Victory" for the BBC.
 For the Yesterday channel he has narrated "Nazi Hunters", "Nazi Collaborators", "Secret War", "Great Crimes and Trials" and "Black Ops".
 He has also voiced many others for Discovery and Channel 4 amongst others.
London Recruits: The Secret War Against Apartheid is a 2012 book edited and compiled by Ken Keable, with an introduction by Ronnie Kasrils and a foreword by Pallo Jordan.

The four orchestral suites (called ouvertures by their author), BWV 1066–1069 are four suites by Johann Sebastian Bach.
 The name "ouverture" refers only in part to the opening movement in the style of the French overture, in which a majestic opening section in relatively slow dotted-note rhythm in duple meter is followed by a fast fugal section, then rounded off with a short recapitulation of the opening music.
 More broadly, the term was used in Baroque Germany for a suite of dance-pieces in French Baroque style preceded by such an ouverture.
 This genre was extremely popular in Germany during Bach's day, and he showed far less interest in it than was usual: Robin Stowell writes that "Telemann's 135 surviving examples [represent] only a fraction of those he is known to have written"; Christoph Graupner left 85; and Johann Friedrich Fasch left almost 100.
 Bach did write several other ouverture (suites) for solo instruments, notably the Cello Suite no. 5, BWV 1011, which also exists in the autograph Lute Suite in G minor, BWV 995, the Keyboard Partita no. 4 in D, BWV 828, and the Overture in the French style, BWV 831 for keyboard.
 The two keyboard works are among the few Bach published, and he prepared the lute suite for a "Monsieur Schouster," presumably for a fee, so all three may attest to the form's popularity.
Leslie Osborne (1905–1990) was an English composer of light music and themes for television and radio.
 As a composer he wrote a number of lighter orchestral pieces such as "Lullaby for Penelope", although nowadays he is perhaps best known for co-composing the original theme to the BBC soap opera "EastEnders" with Simon May, in 1984.
 Other television credits include "The Secret War", "Cold Warrior" and "Howards' Way".
The Secret War was a seven–part television series produced by the BBC in conjunction with the Imperial War Museum documenting various technical developments during the Second World War.
 It was aired during 1977 and presented by William Woollard.
 The programme opening music was an excerpt from Mussorgsky's "Pictures at an Exhibition".
 The closing music was by the BBC Radiophonic Workshop.
 The 'seventh' episode (The Battle of the Atlantic) often included with video versions of the series was not part of the original series but produced separately.
Albert Eugene Kahn (May 11, 1912 – September 15, 1979) was an American journalist, photographer, author and nephew of modernist industrial architect Albert Kahn.
 He is mostly known as author of books "Sabotage!
 The Secret War Against America" and "The Great Conspiracy: The Secret War Against Soviet Russia" which described the defendants at the Moscow Trials as guilty.
 Albert E. Kahn's father, Moritz Kahn, was senior engineer in the firm who set up the Kahn brothers Soviet Union operation in conjunction with Gosproekstroi.
Pictures at an Exhibition (Russian: Картинки с выставки – Воспоминание о Викторе Гартмане , "Kartínki s výstavki – Vospominániye o Víktore Gártmane" , "Pictures from an Exhibition – A Remembrance of Viktor Hartmann"; French: "Tableaux d'une exposition" ) is a suite of ten pieces (plus a recurring, varied Promenade) composed for the piano by Russian composer Modest Mussorgsky in 1874.
"Gran Turismo" featured two different opening songs.
 For the North American and PAL versions is a Chemical Brothers remix of the Manic Street Preachers song Everything Must Go.
 The opening music for the Japanese version is "Moon Over The Castle", composed by Masahiro Andoh; this music is used for the opening movie in the Japanese version of every "Gran Turismo" primary game to date (as well as the Asian version of Gran Turismo 4).
 The North American and PAL versions of the game featured a soundtrack composed of instrumentals and famous bands, whereas the Japanese version used the "Gran Turismo Original Soundtrack", a completely original score.
Match Day is a football computer game, published by Ocean Software in 1984, originally on the ZX Spectrum and then later released on the Amstrad CPC, BBC Micro, & Commodore 64 systems.
 It is the first game in the "Match Day" series, and the title and opening music are references to "Match of the Day".
 It was the creation of programmer Jon Ritman.
 The BBC Micro version was ported by Chris Roberts.
