You may have noticed that, currently, there is a vacancy in the field of TV motoring journalism. Everyone from actor Philip Glenister to Mr Blobby has been suggested as the person to replace Jeremy Clarkson on Top Gear after he was sacked for punching a producer. Yet for me, the replacement has been hiding in plain sight, wearing a paperboy cap. Brian Johnson, the lead singer of AC/DC, the man with a voice like a rasping V8, is another curly-haired straight talker who knows how to command an audience. He wears much better jeans than Clarkson, and as the frontman of a band that has sold more than 200 million records over 40 years, he’s much more successful. He also has the relevant experience.
