The show opened on Tuesday morning, with a lively song-and-dance routine involving dancers dressed as monks, Italian scenery (a nod to Renaissance cryptographer Leon Battista Alberti) and a new version of Queen's Under Pressure.

Lyrical flourishes included: "It's the pressure of knowing what some hack might clean out. Having no defence, feeling dread and doubt", and references to IT managers being "Under Pressure" from malware and rootkits.

Stirring stuff, especially at the end when the monks scarpered offstage like the children of Hamlyn.

Appropriately, we then got to hear from the company whose software is targeted by many of these threats — Microsoft.
