In 2003, Detroit beef-rock howlers Electric Six rode into the Concorde on a giddy wave of mainstream novelty, driven by the massive success of tongue-in-cheek hit Danger! High Voltage.

Six years later, it wouldn’t be unreasonable to anticipate the gag to have well and truly worn off for this feisty bunch of jokers and inimitable frontman Dick Valentine, entering swathed in a shiny purple cape.

But this irrepressible six-piece proved why they have achieved unexpected longevity – powered by a sublimely dextrous drummer, they marry disco guitar riffs (“improper dancing in the middle of the street”) and the muscularity of metal, hitting the spot with most of the jokes on the way.

Formula 409 rested on the line “you can clean your kitchen baby”, and when a gog-eyed Valentine rattled off Gay Bar, the singalong which had been on everyone’s lips long before the preposterous opening chord, it was merely another comedy moment in a blissfully unhinged set.
