Feargal Sharkey was hired as a guest vocalist for the A-side of the group's only single, "Never Never". Clarke and Radcliffe had planned to use a different singer on each track the group recorded, but the group disbanded after the release of "Never Never", and no other vocalists were employed by the duo.
The Assembly marked the most involved phase of Clarke's long-term professional relationship with sound engineer Radcliffe, who had contributed significant influences to the recordings of Clarke's previous bands, Depeche Mode and Yazoo. However, the Assembly project never became a full-fledged band and resulted in only one single release, the UK hit "Never Never". It featured a sampled guitar track triggered note for note on a Fairlight CMI). The sound was augmented by session musician Clem Clempson on electric guitar.
Former Undertones frontman Feargal Sharkey was hired to sing on this track. Clarke and Radcliffe had planned to use a different singer on each track the group recorded, but none were released after "Never Never".
The other track on the single, "Stop/Start," was an instrumental, featuring Clarke's signature songwriting style with syncopation that gradually became the downbeat of the musical phrase.
Despite the commercial success of the single, The Assembly was no longer a functioning entity by the end of 1984. Clarke went on to form Erasure with vocalist and co-songwriter Andy Bell in 1985. Although Erasure worked with Radcliffe on some of their early work, they eventually began working with other producers and engineers, including Flood. Sharkey, for his part, began a successful solo career in 1984 and achieved his only UK number one single in 1985 with "A Good Heart".
"Never Never" was re-released on CD single in 1996 with four tracks, containing both the normal and extended versions of both the title song, and "Stop/Start". The music video for "Never Never", filmed at Upminster Windmill in the London Borough of Havering, was featured on the first Now That's What I Call Music! video in 1983, though it did not feature on the corresponding compilation album.
In May 2011, Sharkey appeared on stage during the Erasure set at Mute Records's Short Circuit music festival for a one-off performance of "Never, Never" with Clarke.
