It was released by Polydor Records and PGP-RTB in September 1981. It was recorded over a period of one month at Compass Point Studios in Nassau, Bahamas with his old writing partner Chas Jankel and the reggae duo Sly and Robbie. It is also the first Dury album distributed by Polydor. It was his first solo album in four years, since New Boots and Panties!! (1977). Alike the aforementioned album, this album covers a diverse range of musical styles reflecting Dury's influences and background in pub rock, taking in funk, disco, British music hall and early rock and roll, courtesy of Dury's musical hero Gene Vincent.
But unlike New Boots... the album was received negatively by the majority of music critics, while other reviewers noted good points to the album. It was a commercial disappointment failing to make the Top 40, and the album's only single, "Spasticus Autisticus", failed to chart.
However, Dury and Jankel were greatly unprepared and without enough material for a new album, so they wrote much of the album either on the plane or at their destination. The final album was eight tracks long, and both of them were ultimately disappointed with it.
While recording the album Dury and Jankel were mobbed by Jamaican band Smokey, who mistook a line from his hit "Reasons to be Cheerful, Part 3" to be about them. The reference to "sing-alonga Smokey" was actually about Smokey Robinson. Dury politely agreed to listen to their new album while his co-writer sneaked away.
Beside Spasticus, another noteworthy track appears on the album; "Girls (Watching)" is the only officially released cover version Ian Dury recorded; it was written by Sly Dunbar. However, MP3s of Dury, performing The Stranglers single "Peaches" and "Bear Cage" live, along with Hazel O'Connor and members of The Stranglers can be found on some download services. As well as being found on two Stranglers live albums And Then There was Three and The Stranglers and Friends – Live in Concert both CDs are of the same gig, when Hugh Cornwell was in prison, various artists including Dury took turns to sing.
Dury himself later admitted that the only track he would have listened to again was "Spasticus". Chas Jankel was a little kinder and continues to praise "Lonely (Town)" as an underrated gem on the album. "The (Body Song)" and "Funky Disco (Pops)" are the tracks most currently selected for greatest hits compilations (along with "Spasticus").
Lord Upminster received negative reviews from contemporary music critics.
In a contemporary review music critic Robert Christgau gave the album a "B-" and panned that "Spasticus Autisticus is every bit as startling as Dury must have hoped after Laughter got lost in the hustle" but added that "I suppose the idea is to let the riddims of Steve Stanley, Chaz Jankel, and Sly & Robbie turn jingles into rallying cries"
In a retrospective review, Stephen Thomas Erlewine of AllMusic gave the album two and a half out of five stars and wrote that "Lord Upminster turned out to be a set of uninspired funk that lacks the joyful energy of his three previous records." And Emma Greatrex of the Daily Express gave the album two stars writing that the album was "largely overlooked", but also noted that "many of the songs are repetitive and indistinguishable from each other".
Some compilations mistakenly do not use parts of the song titles that are in brackets (especially "Spasticus"), it is a 'theme' of the titles on the album and all of them do have words in brackets as shown above.
