He emerges from Vyvyan's full vacuum cleaner bag and ends up being shoved into the fridge by Rick. However, inspection of the episode shows that both Dewison and the fifth housemate appear together in the same shot towards the end of the episode. In an exclusive documentary "How the Young Ones Changed Comedy" that aired in 2018 on Gold, series co-writer Lise Mayer stated that the idea was there had been a party at the student house at some point in the past and there was a person who had just never left. This is why you see them just hanging around. Although the series was set in north London, many external scenes were filmed in Bristol, namely the suburb of Bishopston, where the student house is situated at the top of Codrington Road. Other locations include the Fascist Pig Bank, the Launderette and the Army Careers Office, all around the corner on Gloucester Road. The pub in which Vyvyan's mum works, the Kebab and Calculator in the series, was the Cock of the North (since renamed the Westbury Park Tavern) in Northumbria Drive, Bristol. A brief scene in a pharmacy was filmed outside GK Chemists, now taken over by Lloyds Pharmacy, in St Johns Lane, Bedminster. The shop was renamed "OK Chemists" for the scene, in which Mike goes to buy cough medicine, but orders £180 worth of Durex condoms instead—"Force of habit". All four characters attended the fictional Scumbag College. As Neil sometimes wore a University of London T-shirt, it seems likely that Scumbag is one of the University of London's constituent colleges, although they were never seen attending the institution and were rarely seen studying. The end of the series was not the last appearance of "The Young Ones". For the British charity television appeal Comic Relief, the four recorded a song and video for Cliff Richard's "Living Doll", accompanied by Richard and Shadows guitarist Hank B. Marvin. Alexei Sayle was not involved, as he felt collaborating with Richard was against the alternative ethos of the show, but had already achieved chart success in 1984 with "'Ullo John! Gotta New Motor?". In 1984, Planer released an album of music and skits in character as Neil, entitled "Neil's Heavy Concept Album". Musical direction was by Canterbury scene keyboardist Dave Stewart. It featured Stewart's alums Barbara Gaskin, Jakko Jakszyk, Pip Pyle, Gavin Harrison, Jimmy Hastings and Rick Biddulph.
