Context paragraphs:
Le diable à quatre (ballet): Le Diable à quatre is a ballet in two acts and three scenes (or in three acts), with choreography by Joseph Mazilier, music by Adolphe Adam, and libretto by Adolphe de Leuven, first presented by the Ballet of the Académie Royale de Musique on 11 August 1845, with Carlotta Grisi (as Mazourka) and Lucien Petipa (as Count Polinski).

Le Diable amoureux (ballet): Le Diable amoureux (also known as Satanella or Love and Hell) is a "ballet pantomime" in three acts and eight scenes, originally choreographed by Joseph Mazilier to the music of Napoléon Henri Reber and François Benoist.  The libretto by Jules-Henri Vernoy de Saint-Georges is based on Jacques Cazotte's 1772 occult romance "The Devil in Love".  The work was first presented by the Ballet du Théâtre de l'Académie Royale de Musique in Paris on 23 September 1840, with Pauline Leroux (as Uriel), Mazilier (as Alvaro, for ballet his name is Frederic), and Louise Fitz-James (as Lilia).

Paquita: Paquita is a ballet in two acts and three scenes with music by Édouard Deldevez and Ludwig Minkus, originally choreographed by Joseph Mazilier.

Joseph Mazilier: Joseph Mazilier (1 March 1801, Marseilles – 19 May 1868, Paris) was a 19th-century French dancer, balletmaster and choreographer.  He was born as "Giulio Mazarini".  He was most noted for his ballets "Paquita" (1844) and "Le Corsaire" (1856).  He created the role of James in "La Sylphide" with Marie Taglioni.

The Great Escape (festival): The Great Escape was a music festival held at Newington Armory, located within Sydney Olympic Park that took place in 2006 and 2007.  Initially held over the Easter long weekend for the first two events, in 2008 it was announced the festival would take place on the Labour Day weekend, however the event was cancelled 2 months from the date due to poor ticket sales .  It evolved from the 2005 Cockatoo Island Music Festival.  The music and other attractions run over three full days (Good Friday to Easter Sunday in 2006–07), with some patrons camping from Thursday evening to Monday morning.  Punters could attend either for the full weekend camping, purchase a 3-day pass and commute each day or attend a single day.  Many acts also played the East Coast Blues & Roots Music Festival the same weekend, however The Great Escape line-up is more diverse featuring pop, hip hop, electronic and rock acts that would not fit into a Blues and Roots line-up.  In addition to musical acts, there is also a wide range of other features such as comedy acts, bingo and trivia, conspiracy theory talks and yoga.  There is no immediate future for the Great Escape at this point, but organisers are confident it will be resurrected in the near future.

La reine de Chypre: "La reine de Chypre", first performed at the Salle Le Peletier of the Paris Opéra on 22 December 1841 with Rosine Stoltz in the title role and Gilbert Duprez as Gérard, was regarded in its time as one of the composer's greatest achievements.  Joseph Mazilier was the choreographer, and the ballet starred Adéle Dumilâtre, Natalie Fitzjames, and Pauline Leroux with Marius Petipa and Auguste Mabile.  The publisher Maurice Schlesinger was reputed to have paid the enormous sum of 30,000 francs for the rights to the opera.

Bay City Rollers: The Bay City Rollers are a Scottish pop band whose popularity was highest in the mid 1970s.  The "British Hit Singles & Albums" noted they were "tartan teen sensations from Edinburgh", and were "the first of many acts heralded as the 'biggest group since the Beatles' and one of the most screamed-at teeny-bopper acts of the 1970s".  For a relatively brief, but fervent period (nicknamed "Rollermania"), they were worldwide teen idols.  The group's line-up had numerous changes over the years, but the classic line-up during its heyday included; guitarists Eric Faulkner and Stuart John Wood, singer Les McKeown, bassist Alan Longmuir, and drummer Derek Longmuir.

Budgie (band): Budgie are a Welsh hard rock band from Cardiff.  They are described by author Garry Sharpe-Young as one of the earliest heavy metal bands and a seminal influence to many acts of that scene, with fast, heavy rock (an influence on the new wave of British heavy metal (NWOBHM) and acts such as Metallica) being played as early as 1971.  The band has been noted as "among the heaviest metal of its day".

Le Corsaire: Le Corsaire is a ballet typically presented in three acts, with a libretto originally created by Jules-Henri Vernoy de Saint-Georges loosely based on the poem "The Corsair" by Lord Byron.  Originally choreographed by Joseph Mazilier to the music of Adolphe Adam, it was first presented by the ballet of the Théâtre Impérial de l´Opéra in Paris on 23 January 1856.  All modern productions of "Le Corsaire" are derived from the revivals staged by the Ballet Master Marius Petipa for the Imperial Ballet of St. Petersburg throughout the mid to late 19th century.
