Watch out Martin Rushent. Trevor Horn is snapping hard at your heels. Trev, the goggles behind The Buggles, is rapidly becoming today’s most wanted producer. He’s been working with Dollar now for some time and has just put the final touches to their latest 45, “Give Me Back My Heart”. (The B-side, funnily enough is called “Pink And Blue”. They must be this season’s new colours. The new Altered Images’ album is “Pinky Blue”). ABC’s Horn-honed nugget, “Poison Arrow”, is polevaulting up the charts. And, rumour has it, Orange Juice and even Wah! are thinking of employing the Horn handiwork.
