The Devil's Wall (Czech: Čertova stěna ) is a comic-romantic opera in three acts, with music by Bedřich Smetana and libretto by Eliška Krásnohorská, in their third operatic collaboration.
 The subtext of the plot is a Czech legend of a sheer rockface that overlooks the Vltava river, near the old monastery of Vyšši Brod, where the Devil was said to have halted the building of the monastery by damming the Vltava, which then rose and flooded the site.
Diabolo (ディアボロ ) is a manga by Kaoru Ohashi and Kei Kusunoki.
 The story takes place in Japan.
 The plot revolves around teenagers being converted to followers of the "Diabolo" by a secret society in exchange for the fulfillment of their wishes.
 Teens who have made a pact with the Devil begin to go crazy at age 17, often manifesting in acts of brutality and homicide, and upon turning 18 reach a point of no return to their original selves.
 The phenomenon is a mystery to the adult world and media, who try to ascertain the origin of mass teen violence.
 There are six great spirits (also teenagers) that serve the Devil, each of which has a hand in destroying the world.
 The main characters, Ren and Rai, use their own Devil-given powers to stop them while searching for their cousin Mio, saving other teenagers from their pacts, and racing against their approaching 18th birthdays.
 It describes its plot as "The age where the ensured bend to temptation and slowly fall from human to devil."
 It is published in French by Soleil, and was published in English by Tokyopop.
"Love Bug Leave My Heart Alone" is a 1967 single released by Motown girl group Martha and the Vandellas.
 The song's production was a departure from the Vandellas' repertoire as their label, Motown, was having a harder time staying with the times in the music industry and having a much harder time finding a hit for its acts after several departures including Vandellas collaborators William "Mickey" Stevenson and Holland-Dozier-Holland, who produced the b-side to this single, "One Way Out", one of the trio's final recordings with the Vandellas.
 Produced by Richard Morris, the song displayed of the narrator wanting "the love bug" (i.e., her former lover) to leave her alone so she won't "fall in love".
 The narrator, lead singer Martha Reeves, was left heart-broken the last time she allowed the man to come back to her but after suffering heartbreak, she expresses her disgust at the man's attempts, with her fellow members Rosalind Ashford and Betty Kelley chanting "get outta there, love bug, leave my heart alone".
 The song (with its unusual-for-Motown fuzz guitar) was their second consecutive Top 40 single of 1967 peaking at number twenty-five on the "Billboard" pop singles chart and number fourteen on the Billboard Hot R&B singles chart.
 The record was the first track ever played on UK Radio One by DJ John Peel.
Martha, oder Der Markt zu Richmond ("Martha, or The Market at Richmond") is a "romantic comic" opera in four acts by Friedrich von Flotow set to a German libretto by Friedrich Wilhelm Riese and based on a story by Jules-Henri Vernoy de Saint-Georges.
The Devil in Love (French: Le Diable amoureux ; Russian: Влюблённый дьявол – Vlyublyonny dyavol ) is an opera in three acts by the Russian composer Alexander Vustin (born 1943).
 The Russian libretto was written by Vladimir Khachaturov after the novel "The Devil in Love" by Jacques Cazotte (1772).
Robert le diable ("Robert the Devil") is an opera in five acts composed by Giacomo Meyerbeer from a libretto written by Eugène Scribe and Germain Delavigne.
 "Robert le diable" is regarded as one of the first grand operas at the Paris Opéra.
 It has only a superficial connection to the medieval legend of "Robert the Devil".
Cheever-Cain Ranch is a historic ranch located at 8 Trails End Road in Powder River County, Montana, near the community of Volborg.
 George and Martha Cheever, along with their daughter Lucretia and her husband Ernest Shy, claimed the land under the Homestead Acts in 1905.
 George died in 1908, but the rest of the family built a farmhouse and established a ranching operation on the land.
 The ranch was one of many established in the Pumpkin Creek valley under the Homestead Acts; it also bordered the Custer National Forest, an early attempt to preserve land from overgrazing caused by the multitude of new ranches.
 After Martha Cheever died, Lucretia and Ernest ran the ranch; Ernest later sold the property to the Cain family, with whom he was close friends.
Le diable à quatre ("The Devil to Pay") is an opéra comique in three acts by Christoph Willibald Gluck.
 The French-language libretto is by Michel-Jean Sedaine and Pierre Baurans, after a translation by Claude-Pierre Patu of the 1731 ballad opera by Charles Coffey entitled "The Devil to Pay, or The Wives Metamorphos’d".
 It was first performed at Laxenburg on May 28, 1759.
 The work was a popular success.
 Joseph Haydn used a melody from it, ""Je n’aimais pas le tabac beaucoup" (I didn’t like tobacco much)” in the first movement of his symphony "Le soir".
Swingin' Time was a music variety show, similar to American Bandstand, hosted by WKNR (Keener 13, Detroit) personality Robin Seymour and also, for a time, CKLW radio's Tom Shannon.
 This show was broadcast on CKLW-TV Channel 9 (now CBET-DT) out of Windsor, Ontario Canada, from 1965 to 1968, and also seen in a few other markets in syndication.
 The show featured recording acts, both nationally and locally popular, lip-synching to their latest releases while teenagers showcased the latest dances on the show's dance floor.
 In its brief run, the show featured well-known acts Motown like Smokey Robinson & the Miracles, Marvin Gaye, The Marvelettes, Martha & The Vandellas and The Four Tops, and non-Motown acts such as Bob Seger.
The Devil and Kate, Op.
 112, B.201, ("Čert a Káča" in Czech) is an opera in three acts by Antonín Dvořák to a Czech libretto by Adolf Wenig.
