First of all, I’d like to introduce the interviewer Roger Lewis (left) who was, to me, most unexpected in his approach, the interview was no love in and he was not afraid to challenge David on the basis of his own views and outlook, for example on Brexit. I only know Roger through the blogosphere and the first surprise to me was his appearance. I’d imagined him as the type who went to bed in a suit and tie and only slightly loosened his collar when the temperature exceeded 35 degrees celsius. Instead I was confronted by a sanitised version of Catweasle! Long flowing locks and moustache, I hope he’ll forgive the Catweasle reference, casual clothes but a razor-sharp mind. There was an obvious chemistry between the two so even in times of disagreement there was no shouting across…
