It starred Maynard as Selwyn Froggitt, a hapless but good-natured council labourer, handyman and working men's club secretary in the fictional Yorkshire town of Scarsdale.

Bill Maynard described Froggitt, a burly, balding and good-natured man often clad in a donkey jacket, as "this naïve boy who never grew up".

He lives with his put-upon mother (Megs Jenkins) and his brother Maurice (Robert Keegan), whose romance and eventual marriage to Vera Parkinson (initially played by Rosemary Martin, replaced by Lynda Baron for the second and third series) is sometimes subject to Selwyn's interference.

Froggitt is on the committee of Scarsdale Working Men's Club and Institute, serving as concert secretary in charge of booking "turns".

This version of the programme, retitled Selwyn, featured only Maynard from the earlier series and had Froggitt become entertainments officer under the supervision of manager Mervyn Price (Bernard Gallagher) at the seedy Paradise Valley Holiday Camp.

[2] Bill Maynard had the initial idea for the show, wishing to create a sitcom based around the members of the working men's club in his home village of Sapcote, Leicestershire.

"[6] Additionally, Maynard took inspiration from Shakespeare's A Midsummer Night's Dream, with Froggitt as Bottom and the committee at the working men's club as the mechanicals.

[9] Maynard considered Froggitt's interest in reading The Times an important part of the character, explaining "I wanted him to be intelligent, always anxious to improve himself.

By getting him to read The Times and be an ardent student of dynamic word power, we gave him the breadth to spread the comedy over a wide range of subjects.

[10] Maynard characterised Froggitt as someone who causes havoc simply due to "his tremendous enthusiasm and his willingness to help his fellow man", rather than "an idiot".

As Clarke felt he lacked the familiarity to write about a working men's club, Maynard took the train to Leeds to assist him.

Clarke devised the title Oh No It's Selwyn Froggitt, and the pilot episode was transmitted on 30 September 1974 as part of a six-week season of Yorkshire Television comedy specials.

[10] Megs Jenkins, cast as Froggitt's mother, had initially considered herself the wrong fit for the role and resolved to approach the part straight.

[18] The programme's theme tune was written and composed by Bill Dean, who starred as Jack, and performed by the Tony Mansell Singers.

[19] On transmission, the series became a ratings success, topping the national weekly chart and eventually reaching peak viewing figures of 29 million.

"[23] Martin was replaced by Lynda Baron, who had recently appeared as Nurse Gladys Emmanuel in the first series of Open All Hours.

[10] Plater was not involved with this fourth series and Robert Keegan, who had played Maurice, considered the removal of the supporting cast a potential mistake "as I think viewers of situation comedy like to get to know lots of characters".

[37] Celia Andrews of the Western Daily Press praised "the touch of naivete" in Maynard's performance, describing Froggitt as "a sort of human Aunt Sally meeting life's slings and arrows with a maniacal laugh.

"[38] Reviewing the fourth series, Selwyn, Stafford Hildred of the Birmingham Evening Mail considered the axing of the supporting cast a mistake, commenting "now Mr. Maynard provides most of the humour himself, and the ration of laughs is spread very thin indeed".

"[41] Retrospectively, Oh No It's Selwyn Froggitt has been described as "a kind of Billy Liar for nutters" in The Guinness Book of Classic British TV.
