Cock Sparrer, one of the pioneering Oi! bands, originated in London in 1975 as a pub rock outfit before solidifying their signature sound of loud, raw Cockney anthems. Despite initial record company challenges, they gained momentum in the early '80s, releasing their defining album, Shock Troops, in 1982. This record set the tone for their career with straightforward tunes, forceful guitars, and defiant lyrics belted out by lead singer Colin McFaull. Cock Sparrer's influence extended to a wide range of punk and Oi! bands, inspiring acts like Agnostic Front and Rancid.

After a brief hiatus, Cock Sparrer reemerged in the early '80s amidst the rise of the Oi! movement, solidifying their place as key figures in the genre. Their hit single "England Belongs to Me" during the Falklands War further cemented their status, leading to the release of Shock Troops and subsequent albums. Despite lineup changes and record company disputes, the band persevered, releasing new material in the '90s and 2000s and embarking on extensive tours. Cock Sparrer's enduring legacy was celebrated with their 40th anniversary tour in 2012 and the release of Forever in 2017, showcasing their continued relevance in the punk scene.
