Rock band Sham 69 have a large and loyal following of working-class kids, who call themselves 'The Sham Army'. They have a reputation for causing trouble, and Sham concerts have often been disrupted and brought to an end by fighting. Jimmy Pursey, the lead singer, has struggled to prevent these outbreaks, but the violent and conflicting passions aroused at Sham concerts have placed him in an increasingly difficult position. Sham's latest album 'That's Life' portrays the pressures that face the kids who follow the band. Arena this week recreates scenes from that album and follows the story of one Sham concert which threatened to explode.
