The Donkey Show: A Midsummer Night's Disco is a theatrical adaptation of Shakespeare's "A Midsummer Night's Dream".
 The production, created in a disco-era style, was written by Diane Paulus and her husband Randy Weiner and the members of Project 400, Emily Hellstrom, Jordin Ruderman, Rachel Murdy and Anna Wilson.
 It first appeared Off-Broadway, opening August 18, 1999.
 The show subsequently ran for six years including venues in England, Scotland, France and Spain.
 After a successful run at the Edinburgh Festival the Donkey Show show came to London for a 8 month run in Londons West End (Hanover Grand).
 The London show was produced by David Babani and Graham Kentsley.
 Rob Goodmonson (NYC) played the part of the DJ in the UK production.
 In 2009, the show was revived by the American Repertory Theater in Cambridge, Massachusetts, for which Paulus is Artistic Director.
 The club/theater space used in Cambridge is called OBERON, after the king of the fairies in "A Midsummer Night's Dream".
A Midsummer Night's Dream, Op.
 64, is an opera with music by Benjamin Britten and set to a libretto adapted by the composer and Peter Pears from William Shakespeare's play, "A Midsummer Night's Dream".
 It was premiered on 11 June 1960 at the Aldeburgh Festival, conducted by the composer and with set and costume designs by Carl Toms.
 Stylistically, the work is typical of Britten, with a highly individual sound-world – not strikingly dissonant or atonal, but replete with subtly atmospheric harmonies and tone painting.
 The role of Oberon was composed for the countertenor Alfred Deller.
 Atypically for Britten, the opera did not include a leading role for his partner Pears, who instead was given the comic drag role of Flute/Thisbe.
Luciano Mariani (1801 – 10 June 1859) was an Italian operatic bass.
 Amongst the several roles he created were Rodolfo in Bellini's "La sonnambula" [Milan, Teatro Carcano, 1831], Alfonso d'Este in Donizetti's "Lucrezia Borgia" and Oroe in Rossini's "Semiramide".
 His elder sister, Rosa Mariani, was also an opera singer (contralto) and sang Arsace in the premiere of "Semiramide".
 They toured Italy singing together in many operas.
 Mariani sang in Lisbon at the Teatro São Carlos from 1839 to 1840, where he appeared in several Portuguese premieres of Italian operas, as well as the world premieres of Antonio Luís Miró's opera "Virginia" and Manuel Inocêncio Liberato dos Santos's opera "Inês de Castro".
 Mariani was born in Cremona and died in Castell'Arquato, aged 58.
The Princess's Theatre or Princess Theatre was a theatre in Oxford Street, London.
 The building opened in 1828 as the "Queen's Bazaar" and housed a diorama by Clarkson Stanfield and David Roberts.
 It was converted into a theatre and opened in 1836 as the Princess's Theatre, named for then Princess Victoria before her accession as queen.
 After an unsuccessful series of promenade concerts, alterations were made on the interior, and the theatre was reopened on 26 December 1842 with Vincenzo Bellini's opera "La sonnambula".
 The theatre, by now under the management of John Medex Maddox, presented operas and other entertainments, such as General Tom Thumb.
Midsummer Dream (Spanish: El Sueño de una noche de San Juan , meaning "A Dream of a Night of Saint John", the feast of Saint John, celebrated on the night of June 23, being the traditional midsummer feast in Spain and Portugal) is a 2005 computer-animated film from Dygra Films, the creators of "The Living Forest".
 Made in Spain and Portugal, the film is loosely based on William Shakespeare's play "A Midsummer Night's Dream".
La sonnambula "(The Sleepwalker)" is a ballet by the co-founder and ballet master of New York City Ballet, George Balanchine, made to Vittorio Rieti's music using themes from the operas of Vincenzo Bellini including "La Sonnambula", "Norma", "I Puritani" and "I Capuleti e i Montecchi" (1830–35) and with costumes by Karinska.
 The premiere took place with the Ballet Russe de Monte Carlo on Wednesday, 27 February , at City Center of Music and Drama, New York; the City Ballet premiere was on 6 January 1965.
La sonnambula ("The Sleepwalker") is an opera semiseria in two acts, with music in the "bel canto" tradition by Vincenzo Bellini set to an Italian libretto by Felice Romani, based on a scenario for a "ballet-pantomime" written by Eugène Scribe and choreographed by Jean-Pierre Aumer called "La somnambule, ou L'arrivée d'un nouveau seigneur".
 The ballet had premiered in Paris in September 1827 at the height of a fashion for stage works incorporating somnambulism.
Tenore di grazia , also called leggero tenor ("graceful" and "light" tenor, respectively), is a lightweight, flexible tenor voice type.
 The tenor roles written in the early 19th-century Italian operas are invariably leggero tenor roles, especially those by Rossini such as Lindoro in "L'italiana in Algeri", Don Ramiro in "La Cenerentola", and Almaviva in "Il barbiere di Siviglia"; and those by Bellini such as Gualtiero in "Il pirata", Elvino in "La sonnambula" and Arturo in "I puritani".
 Many Donizetti roles, such as Nemorino in "L'elisir d'amore" and Ernesto in "Don Pasquale", Tonio in "La fille du régiment", are also "tenore di grazia" roles.
 One of the most famous leggero tenors of that period was Giovanni Battista Rubini, for whom Bellini wrote nearly all his operas.
A Midsummer Night's Dream is a two-act ballet choreographed by George Balanchine to Felix Mendelssohn's music to Shakespeare's play of the same name.
 In addition to the incidental music, Balanchine incorporated other Mendelssohn works into the ballet, including the Overtures to "Athalie", "Son and Stranger", and "The Fair Melusine", the "String Symphony No. 9 in C minor" and "The First Walpurgis Night".
 "A Midsummer Night's Dream", Balanchine's first completely original full-length ballet, premiered at New York City Ballet on 17 January 1962, with Edward Villella in the role of Oberon, Melissa Hayden in the role of Titania, and Arthur Mitchell in the role of Puck.
 The ballet employs a large children's corps de ballet.
 Act I tells Shakespeare's familiar story of lovers and fairies while Act II presents a strictly classical dance wedding celebration.
 The ballet dispenses with Shakespeare's play-within-a-play finale.
 "A Midsummer Night's Dream" opened The New York City Ballet's first season at the New York State Theater in April, 1964.

 Considered one of the finest coloratura sopranos of the late 19th and early 20th centuries, her most famous roles were Amina in "La sonnambula", and the title roles in "Lakmé", "Mignon", "Mireille", and "Lucia di Lammermoor.
