One of those curious bands who are reasonably successful in Britain but struggle for recognition at home, We Are Scientists specialise in perky, undemanding but relentless pop-punk. They are the Californian Busted, with jowls rather than cheekbones.

Over the course of 70 feverish minutes, they rattled through 19 brisk songs to the delight of their young audience, pausing only for a neat line in knowing wit (“Excellent,” smiled bassist Chris Cain, after the rapturously received third song This Scene Is Dead, “we can just coast from here, I feel.”) and moments of eyebrow-raising peculiarity: the surprisingly complex Beach Boys-esque harmonies of Can’t Lose and the almost reggaefied Textbook.

The unyielding barrage took its toll (I haven’t pined for a ballad with such unrequited longing since I grappled with Motörhead) and the fact they played more songs from their previous album than their current one suggested they understand that their creative fires are waning.

Any hope lies not merely in their unceasingly sunny disposition but in the turbo-charged It’s A Hit and the adored The Great Escape, which, for a heady moment, felt like the anthem of a generation.
