At what was intended to be Sham's final concert at the Glasgow Apollo Theatre on June 29 1979 Jones and Cook had joined Sham onstage for the encore of "Pretty Vacant", "White Riot", "If the Kids are United" and "What Have We Got"? This was to be the start of the new band. Time was spent in the studio where two songs were recorded - "Some Play Dirty" and "Natural Born Killer" (which was later reworked as The Professionals' "Kick Down the Doors"). However problems around deciding the name of the new group (Pursey favoured using 'The Sex Pistols'), and arguments within the band meant that it was not to be. On 19 August Jones and Cook walked out of a recording session with Jones saying "It's worse than working with Rotten". The studio recordings have never seen the light of day, but the encore at the Glasgow Apollo was released on Sham's Last Stand and Sham 69 Live in Glasgow 1979. The latter miscredits the Sham song "George Davis is Innocent (also known as "The Cockney Kids are Innocent" and "Everybody's Innocent") as the Sex Pistols' "No One is Innocent".
After the dissolution of the band, Cook and Jones went on to form The Professionals, and Pursey moved on to solo projects, later reforming Sham 69.
