Joined by Luke Rendle (drums), Steve Guthrie (guitar), and John Lennard (saxophone), bassist Stan Stammers completed Brandon's line-up to form Theatre of Hate; the Werner brothers subsequently joined The Straps, the street punk band Stammers had played for prior.

In August 1981, Mick Jones of The Clash produced Westworld, Theatre of Hate's first (and only) studio album to be released prior to the band's dissolution the following year.

[6] Guitarist Billy Duffy (formerly of The Nosebleeds) joined the band soon after the album had been recorded, and drummer Rendle was replaced by Nigel Preston.

[3] In 1994, a line-up of Brandon, Stammers, guitarist John McNutt and drummer Art Smith went into Mix-O-Lydian Studio in Boonton, New Jersey with producer Brad Morrison to record a new album under the Theatre of Hate banner.

A 1996 tour featuring a line-up of Brandon, McNutt, Smith and new bassist Knut Knutson resulted in the live album Retribution Over the Westworld, issued that year by Receiver Records.

Another album of 1982 material recorded with Jones, Aria of the Devil, was released in 1998 by Snapper Music, while Live at the Lyceum was reissued as Love Is a Ghost in 2000.

[6] To coincide with Westworld's 25th anniversary, Theatre of Hate reformed for a week-long tour culminating at the Carling Academy Islington on 29 April 2007.

[17] Replacing him was Craig Adams (former bassist for numerous bands including The Sisters of Mercy, The Mission, The Cult, The Alarm and Spear of Destiny), joining Brandon, Guthrie, Lennard and Rendle for the reunion.

In May 2012, Theatre of Hate, with a line-up of Brandon, Stammers and Lennard, augmented by Adrian Portas (New Model Army, Sex Gang Children, Spear of Destiny) on guitar and Mike Kelly on drums, reunited again for three Westworld 30th anniversary concerts, held in Bristol, London and Crewe.
