"O" (also known as "O (Fly On)") is a song by British rock band Coldplay for their sixth studio album "Ghost Stories" (2014).
 It appears as the ninth and final song on the album.
 It is divided in two different songs: "Fly On" (0:00–3:54) and "O" (6:18–7:47), in the standard edition of "Ghost Stories" between the two songs there are more than two minutes of silence while in the Target deluxe edition there is no silence.
 The song has charted in England and in France.
 A live version of the track recorded at the Royce Hall of Los Angeles appears in the "Ghost Stories Live 2014".
Ghost Stories was a U.S. pulp magazine that published 64 issues between 1926 and 1932.
 It was one of the earliest competitors to "Weird Tales", the first magazine to specialize in the fantasy and occult fiction genre.
 It was a companion magazine to "True Story" and "True Detective Stories", and focused almost entirely on stories about ghosts, many of which were written by staff writers but presented under pseudonyms as true confessions.
 These were often accompanied by faked photographs to make the stories appear more believable.
 "Ghost Stories" also ran original and reprinted contributions, including works by Robert E. Howard, Carl Jacobi, and Frank Belknap Long.
 Among the reprints were Agatha Christie's "The Last Seance" (under the title "The Woman Who Stole a Ghost"), several stories by H.G. Wells, and Charles Dickens' "The Signal-Man".
 The magazine was initially successful, but began to lose readers, and in 1930 was sold to Harold Hersey.
 Hersey was unable to reverse the magazine's decline, and "Ghost Stories" ceased publication at the start of 1932.
The Collected Ghost Stories of M. R. James is the title of M. R. James' omnibus collection of ghost stories, published in 1931, bringing together all but four of his ghost stories (which had yet to be published).
Patrick Macnee's Ghost Stories, also known as "Ghost Stories", "Ghost Stories: A Paranormal Insight", and "Real Ghost Stories", was a series of six specials that were originally released on 10 October 1997.
 The specials were hosted by Patrick Macnee (of TV's "The Avengers" and "The Howling".)
 The six specials were released separately and together on VHS and in several boxed sets on DVD.
 The specials investigate various hauntings and is similar to the format of "Unsolved Mysteries".
 The series include such explorations as the legends of "The Black Hope Horror", "The Tower of London", "Harriet’s Ghost" and many more.
"Midnight" is a song by British rock band Coldplay for their sixth studio album, "Ghost Stories" (2014).
 It was written and produced by band members Guy Berryman, Jonny Buckland, Will Champion and Chris Martin, with production assistance from Paul Epworth, Daniel Green, and Rik Simpson, and co-production from Jon Hopkins.
 A music video for the "Ghost Stories" track was released on 25 February 2014 as a teaser for the then-unannounced sixth studio album.
 A promotional "Midnight" 7-inch vinyl single was pressed by Parlophone for Record Store Day 2014.

Ghost Stories Live 2014 is the fourth live album and a concert film by the British alternative rock band Coldplay.
 The album, a live recorded version of the band's sixth studio album "Ghost Stories", was released by Parlophone in the United Kingdom on 24 November 2014.
 A DVD from one of the "Ghost Stories" concerts that was filmed at Sony Studios, Los Angeles in March 2014, is included with the Live CD.
 The performance was previously shown on NBC, however it differs from the TV special as it only includes the performances of the songs from "Ghost Stories" and the NBC special only featured 6 songs from "Ghost Stories" and the previous hits, "Clocks," "Viva la Vida," and "Paradise".
 According to the band's official website, it was filmed by Grammy Award-nominated director Paul Dugdale, in a custom-built amphitheatre at Sony Studios, Los Angeles, the ground-breaking production sets the band's performance against stunning 360-degree and overhead imagery.
What Shadows We Pursue (2003), subtitled "Ghost Stories, Volume Two", is a posthumously published collection of short stories by Russell Kirk (1918–1994).
 It is the second of two such hardcover collections from Ash-Tree Press, a noted contemporary publisher of classic ghost stories.
 Together with the previous companion volume, "Off the Sand Road" (2002), it contains the entire corpus of Kirk's short fiction—the only such undertaking by any publisher—including some pieces not easily categorized as ghost stories.
More Ghost Stories is the title of M. R. James's second collection of ghost stories, published in 1911.
 Some later editions under the title "Ghost Stories of an Antiquary" contain it and the earlier "Ghost Stories of an Antiquary" in one volume.
