Unwinese was a corrupted form of English in which many of the words were altered in playful and humorous ways, as in its description of Elvis Presley and his contemporaries as being "wasp-waist and swivel-hippy".

Unwin's early career and training introduced him to wireless and radio communication, and this, coupled with work in the BBC's War Reporting Unit from about 1944, ultimately proved to be his passage into the media.

The recording was broadcast on Pat Dixon's Mirror of the Month programme and a favourable audience reaction led to the commissioning of another sketch in which Unwin, playing an inhabitant of Atlantis, was interviewed about life in the sunken city.

When Lew Grade, Anderson's financial backer and head of distributor ITC, was introduced to the Unwinese dialogue, he cancelled the production on the basis that he believed viewers would not understand what Unwin was saying, despite the fact that such confusion was intentional.

In 1994, Unwin collaborated with British dance music act Wubble-U on their single "Petal"; on its re-release in 1998, the track ranked number 55 in the UK Chart.

In 1998, Unwin made a cameo appearance in the Aardman Animations series Rex the Runt, as an accountant who speaks largely in fairly standard English, occasionally lapsing inexplicably into Unwinese.

Unwinese, also known as "Basic Engly Twenty Fido", was an ornamented and mangled form of English in which many of the words were deliberately corrupted in a playful and humorous manner, but which was still largely comprehensible to the listener.

For example, in his talk on music, "Populode of the Musicolly", Unwin says:[7] They do in fact go back to Ethelrebbers Unready, King Albert's burnt capers where, you know, the toast fell in and the dear lady did get a very cross knit and smote him across the eardrome excallybold.

[8]Unwinese has been compared to Lewis Carroll's nonsense poetry, such as Jabberwocky, where the sentences sound superficially like English when read aloud, but their precise meaning is unclear.

Suns of Arqa released a tribute album to Unwin (entitled "Tributey") following his death, featuring a selection of his works with the band over the years, as well as various interviews.
