Darren and Andrew look like two East End plumbers who’ve turned up to fix Barbara Windsor’s downstairs leak. They’re the last people you’d imagine could be an ace mind-reading act.

Formerly two independent Magic Circle members, DNA were catapulted from auditions to final of Britain’s Got Talent 2017 and despite finishing last became more popular than the winner, after they muffed a trick on live television.

A lot of the live touring act repeats the material seen on the show – with audience members standing in for Simon Cowell or Amanda Holden as they divine a name and telephone number held in a mobile phone, or the street address, name and colour of the living room wall of a friend.

They use a lot of audience members – and the more you or someone you know is the subject of a trick, the more baffling it becomes. I have no idea how the one on stage ‘read’ the serial number on a £20 note I’d pulled from my pocket in the audience.

According to psychologists, mind reading is a science, not a magic trick. Human brains process electrical activity during the thought process and if you can monitor that, you know what we’re thinking. Or, as at the University of Central Lancashire, you can run a Scalextric set powered only by the minds of the players.

I’ve seen some of this done before, at Edinburgh for example by brilliant solo exponents like Ben Hanlin and Colin Cloud, especially the numerical or word-on-a-page-of-a-book reveals. Doing them in a double act can sometimes suggest there’s coded messages passed between the two magicians, but it’s extremely hard to spot it or to be sure.

Having said that, there’s a degree of repetitiveness in the formula of their performed items, and I think they’re still deciding where their public persona should fall – either as the Chas ’n Dave of the magic circuit, or something more smoothly approaching Ant and Dec.

I’d ramp up the cockney if I were you, lads, nobody wants to be Ant and Dec.

touring until 29 March. Dates here
