Hog Wild is a 1980 Canadian comedy film directed by Les Rose and written by Andrew Peter Marin.

Rose Laurens, previously billed as Rose Merryl (born Rose Podwojny on March 4, 1953), is a French singer-songwriter, particularly famous for her 1982 smash single "Africa", number three hit in many European countries.
 She was also the singer for the original version of "J'avais rêvé d'une autre vie" from the French concept album of Les Misérables, a song later adapted into English as "I Dreamed a Dream".
"I Dreamed a Dream" is a song from the musical "Les Misérables".
 It is a solo that is sung by the character Fantine during the first act.
 The music is by Claude-Michel Schönberg, with orchestrations by John Cameron.
 The English lyrics are by Herbert Kretzmer, based on the original French libretto by Alain Boublil and Jean-Marc Natel from the original French production.
"Africa", also titled "Africa (Voodoo Master)", is a 1982 song recorded by French singer Rose Laurens.
 It was one of the singles from her second album "Déraisonnable" and was released in 1982 in France, and in March 1983 elsewhere.
 The version available on the 7" is shorter than on the album, as the musical bridge is shortened and there are fewer refrains.
 It immediately became a smash hit in many countries, reaching the top of the charts.
 In 1994, a CD maxi of remixes was released, but failed to chart.
Three Card Monte is a Canadian crime drama film, released in 1978.
 Directed by Les Rose, the film stars Richard Gabourie as Busher, a small-time con man who meets and becomes a father figure to a runaway kid named Toby (Chris Langevin).
The first act involves Eddie and Richie on a similar tropical island to the one from "".
 However, this is effectively a "play within a play": after the first act, the pair are on their way to the bar when they fall down chutes into a grey dome (""like the Millennium Dome, only fuller")" in which they become trapped.
 After a couple of escape attempts, Eddie eventually finds a bar behind the set and at the end of the show he and Richie perform a song about underpants.
 The song is also performed at the finale of the .
"Memory", often incorrectly called "Memories", is a show tune from the 1981 musical "Cats".
 It is sung by the character Grizabella, a one-time glamour cat who is now only a shell of her former self.
 The song is a nostalgic remembrance of her glorious past and a declaration of her wish to start a new life.
 Sung briefly in the first act and in full near the end of the show, "Memory" is the climax of the musical, and by far its most popular and well-known song.
 Elaine Paige originated the role of Grizabella in the West End production of "Cats", the first to publicly perform the song on stage and bringing attention to its writers Andrew Lloyd Webber and Trevor Nunn, who received the 1981 Ivor Novello award for Best Song Musically and Lyrically.
"Mes amis, écoutez l'histoire", is a tenor aria in Adolphe Adam's 1836 opera "Le postillon de Lonjumeau".
 The D in the final verse is the highest commonly sung note for tenors in opera.
 Donizetti wrote an E♭ for Edgardo in the first act of his opera "Lucia di Lammermoor", though it is very seldom sung.
 Higher notes are occasionally sung in interpolations and ornaments in other bel canto operas, and exceptionally the written F at the end of "Credeasi, misera" in Bellini's "I puritani".

The Noblewoman Vera Sheloga (Russian: Боярыня Вера Шелога, "Boyarïnya Vera Sheloga" ) is an opera in one act by Nikolai Rimsky-Korsakov.
 Rimsky-Korsakov wrote the libretto, which he based on the first act of the play "The Maid of Pskov" by Lev Alexandrovich Mey.
 The opera was composed in 1898 from material omitted from the second version of Rimsky-Korsakov's setting of the play as an opera.
 The first and third versions of the opera "The Maid of Pskov" omit the first act of the play.
