Section 25 formed in Poulton-le-Fylde near Blackpool, Lancashire, in November 1977. Initially the band was a duo, consisting of brothers Larry Cassidy (bass, vocals) and Vincent Cassidy (drums). In June 1978 they made their live debut with Phil Denton on guitar. Denton was replaced in November by Paul Wiggin. June 1979 saw the Cassidy brothers promote a charity gig in aid of International Year of the Child at Blackpool Imperial Hotel, featuring Section 25 and other local bands as well as Joy Division and Orchestral Manoeuvres in the Dark. As a result, Section 25 were invited to play at the Russell Club in Manchester, and joined Factory Records.
