Ho hum. Bit icky. Not bad. Hardly dazzling. The lukewarm response to An Audience With Jimmy Savile has astonished me. This is the best docudrama I’ve seen on stage. From the early 1970s, Britain swooned before Savile. Marketing pollsters found him the country’s best-loved celeb (bar the Queen Mum). He enforced his influence by winning over several establishments at once, the royals, the Beeb, the NHS, the media, the charity sector, Westminster.
