Composition
The single criticises the Identity Cards Act 2006. A statement from the band cited the issue as the reason that Tennant ceased his well-publicized support of Tony Blair's Labour party. The lyrics are fully masked and converted to the homage to Yevgeny Zamyatin's dystopian novel We, in which the inhabitants of the future One State try to build The Integral, a glass spaceship, in order to solve the cosmic equation and resolve all the problems in their One State.
