The show had an ensemble cast amongst others, Sandi Toksvig, Neil Buchanan, Patrick Doyle, Andrea Arnold, Kim Goody and Kate Copstick.

Dawn Lodge (Andrea Arnold), the roller-boot-wearing female lodger, quickly became the go-to person for the animal spot with international vet David Taylor.

Each episode ended with Ethel hosting the ("daring, dazzling, death-defyingly dull, devastatingly dangerous, delectable, delicatestible, divinely decadent") Sandwich Quiz, a madcap-general knowledge game pitting two of that week's guests against each other.

In this series, Sandi and the resident inventor, Tony English, created the Hover Cupboard and later tested it out at sea travelling from Southampton to Cowes on the Isle of Wight.

Tony Deal appeared in two memorable episodes, first on the run from the police and then trying to lure the guest to No 75 with Martin Edwards, but disappeared by the end of the series.

It was revealed in passing that Ethel had emigrated to Australia to live with her cousin, leaving Harry, Dawn, Neil and Kim collectively in charge.

Former member of Copy Cats Andrew O'Connor moved in, while Scottish housekeeper Maisie McConachie (Kate Copstick) became the new resident klutz.

On 7 March 1987, the day after the sinking of the Herald of Free Enterprise, when breaking off for a news report on the disaster, a humorous caption read "sea you later", unwittingly giving the impression of callousness.

J.C. Birch finally saw fit to tear down the entire street and build a Wild West theme park in January, and from then on the show was called "7T3".

Local shop keeper Mr Pattels gave the residents of No 73 a special offer on developing their Super 8 home movies, and even went to the trouble of editing the scenes together.

This first production starred Ethel (Sandi Toksvig), Harry (Nick Staverson), Dawn (Andrea Arnold) and Alec (Patrick Doyle).

Having missed out of the first production, three other prominent members of the revolving No 73 cast joined Ethel in a 1920s murder mystery inspired by, if not exactly written by Agatha Christie.

Ethel, Martin (Richard Addison), Hazel (Jeannie Crowther) and Fred (Tony Aitken) divided all speaking parts between them, though they started off with considerably fewer characters than the Roman production, and the cast-list predictably grew slimmer by the episode.

(20 September 1986 – 25 October 1986) Convicted as toddlers of a crime they did not commit, Corporal Tom "Cannibal" Stiff (Neil), Dimpleton 'Skates' Wreck (Dawn), Marginally Mental Murky (Kim) and Mr. P as B.A.

Police 5's Shaw Taylor appeared in the first and last chapter as kidnap victim of the evil Pirates (also played by Neil, Dawn, Kim and Harry).
