and Diminished Responsibility have also been reissued and Cleopatra Records has released an expanded version of Endangered Species. In September 2021, to celebrate 40 years since the band's concert at Gossips, the official live cassette of the show was rereleased on CD and Download as Danger: The Chaos Tape via Cherry Red. On 17 October 2021, Alvin Gibbs announced on Facebook that "Charlie Harper, Steve Straughan and I have decided Jamie Oliver will no longer continue as drummer for the UK Subs" over his "his post seemingly celebrating the tragic and abhorrent death of Conservative MP, David Amess". Anti-Pasti drummer, Kevin Nixon, agreed to temporarily take over the role vacated by Oliver, enabling the band to meet live commitments in France in October 2021. In what was advertised as the U.K. Subs' final album, Reverse Engineering - a studio record of new material - was released on 1 July 2022. On 20 August 2022, the band played what was billed as their "last ever" show on the island of Ireland, performing at Voodoo in Belfast. Former drummer Steve Roberts died on 13 October 2022. In December 2022 the band announced their drummer Dave Humphries has left the band. European and UK tours planned for 2023 were advertised as being the "final full" tours by the U.K. Subs. The band added: "Rest assured - the band will then continue to play Festivals and the occasional mini weekend tour in various countries as and when." Album titles and later releases Successive U.K. Subs album titles start with consecutive letters of the alphabet, although the band released several live albums and compilations that were not part of the 26 alphabetical titles. All but one of their 21 studio albums are a part of this 26 album sequence while the two albums consisting solely of covers are not part of the sequence. The six non-studio albums in the sequence comprise four live albums, Sub Mission: The Best of the U.K. Subs 1982–1998, a compilation album which also contained a bonus disc with a live recording from a show in Bristol in 1991, and Peel Sessions which compiled their three late 1970's sessions with BBC DJ John Peel. In May 2016, the band released an album starting with the letter "Z", Ziezo, which completed their alphabetical series of album titles. The album was recorded in November 2015 at Perry Vale Studios in South London. At
