 It was first aired on 27 December 2016 on BBC Two.

 Stylistically, it took heavy inspiration from classic 1970s anthology programmes, such as "Beasts", "Thriller", "Tales of the Unexpected" and "Armchair Theatre", and was filmed using authentic equipment.
 Pemberton intended the episode to be a recreation of this kind of classic programming, with critics characterising it as a homage, pastiche or loving parody.
The V.I.P.s were a British R&B musical ensemble formed in Carlisle, Cumberland, (North West England) in late 1963, out of an earlier outfit known as The Ramrods, who had formed in Carlisle in 1960.
 After a change of personnel in April 1967, the band changed their name to "Art", and released the album "Supernatural Fairy Tales".
 They also participated to a psychedelic bizarre album called "Featuring The Human Host And The Heavy Metal Kids" by a collective known as Hapshash and the Coloured Coat, formed by Guy Stevens and an influential British graphic design and avant-garde musical partnership between Michael English and Nigel Waymouth.
 The musicians involved in that project were Mike Harrison on keys and vocals, Luther Grosvenor on guitars, Greg Ridley on bass and Mike Kellie on drums, as well as performances by Stevens, English and Waymouth.
 It was the first time that the term "heavy metal" was ever used in music, even though that album had nothing to do with heavy metal music, being closer to psychedelic music.
 That album was published in 1967 on Liberty Records and contained only five songs from two minutes to more than 15 minutes of psychedelic and almost meditative state kind of music.
