Cockney Rejects are an English punk rock band that formed in the East End of London in 1978. Their 1980 song "Oi, Oi, Oi" was the inspiration for the name of the Oi! music genre. The band members are loyal supporters of West Ham United F.C., and pay tribute to the club with their hit cover version of "I'm Forever Blowing Bubbles", a song which has been sung by the West Ham supporters at matches since the 1980s.
The violence depicted in their lyrics was often mirrored at their concerts, and the band members often fought to defend themselves (often from supporters of opposing football teams) or to split up conflicts between audience members.
Cockney Rejects expressed contempt for all politicians in their lyrics, and they rejected media claims that they had a British Movement following, or that the band members supported the views of that far right group.
