Shelley recorded a new version of "Homosapien", called "Homosapien II", in 1989. The single featured four mixes of the new recording. He played with various other musicians during his career, including the Invisible Girls who backed punk poet John Cooper Clarke. Shelley also formed a short-lived band called the Tiller Boys. He briefly reunited with Howard Devoto to make the LP Buzzkunst, released in 2002. Shelley appeared on the 2005 debut EP by the Los Angeles band the Adored, who toured with Buzzcocks the following year.
Buzzcocks reunited in 1989 and released a new full-length album, Trade Test Transmissions, in 1993. They continued to tour and record and released the album The Way in 2014. In 2005 Shelley re-recorded "Ever Fallen in Love" with an all-star group, including Roger Daltrey, David Gilmour, Peter Hook, Elton John, Robert Plant and several contemporary bands, as a tribute to John Peel; proceeds went to Amnesty International. Shelley performed the song live at the 2005 UK Music Hall of Fame.
