I’d seen enough of Boy George and Marilyn by 1984 to recognise a man in drag. Imagine my surprise when this lot turned out to be genuine sisters, albeit with fierce looks and a vocal range to embarrass Rula Lenska.

The song has dated but it’s still a stirring mix of Chic, electro and Jam & Lewis, as if it passes the baton from disco to modern r’n’b. The delivery is robotic, the lyrics listing the mechanics of lust; if they’d kept the fourth member, they could’ve been the Barbies to Kraftwerk’s Kens.

There’d been a Valentine’s Day airing of Will Young’s ‘All Time Love’, but this was the first record today that had Junior beating the sides of the inflatable. She likes a faster tempo, and she can empathise with pushing “a stream of absurdities” from one’s lips. She’s definitely saying “Dada”, though.
