No one escaped the wrath of dysfunctional Berlin teenage siblings Otto and Astrid Rot, who took The White Stripes’ aesthetic and gave it the Spinal Tap treatment.

Two songs in, the houselights were lifted and hiding stragglers at the back were invited to the front to get involved with the show and its devilishly dark camp innuendo, which sent up everything from the straight-edge lifestyle to Eurodisco.

Flying V guitarist and keytar player Otto flirted with the audience girls; his sister slugged vodka and Irn Bru before taking the microphone for a drum-led grunting, groaning orgasmic solo, OMG Yeah, dedicated to one lucky punter.

Because the songs were short on melody, and the lyrics hit-and-miss, Die Roten Punkte were at their best bantering with the audience and playing Astrid’s drinking game, where everyone jumped up and down, mimicking the German arm swinging.

However, there were some great lines and The 4.15 To Spandau Will Not Run was pop parody genius. The best was saved for last: Otto threatened to boycott the encore and ordered everyone out before Astrid tempted him back with sweet tales of childhood. Under a romantic spotlight poor, confused, Otto lurched in for a kiss.
