 On 18 December 1982, the band helped co-ordinate a 24-hour squat in the empty west London Zig Zag club to prove "that the underground punk scene could handle itself responsibly when it had to and that music really could be enjoyed free of the restraints imposed upon it by corporate industry".In 1983 and 1984, Crass were part of the Stop the City actions co-ordinated by London Greenpeace which foreshadowed the anti-globalisation rallies of the early 21st century.Support for these activities was provided in the lyrics and sleeve notes of the band's last single, "You're Already Dead", expressing doubts about their commitment to non-violence.
