So one of Savile’s gimmicks as a DJ was as Teret puts it the “invention of ‘Dance Tempo’” – or perhaps more widely, an almost scientific attention to which beats cause which effects. While it appears Savile had little emotional feeling for music, or love of the music he played, he had a deep appreciation of musical tempo which appeared to be analytic and focused on how to ‘direct’ or ‘conduct’ a dancefloor, full of “punters” as he might call attendees at his club. And as simple as it being a ‘smooch’ session or a ‘dance’ session he took a long hard look at what kind of ‘control’ or ‘power’ this represented to him: “It’s not power, it’s an effect” as applied to other areas of his life. Savile’s keen sense of opportunity comes with a sharp sense of timing in order to take advantage.

Savile claimed to have naturally strong hypnotic talents , which he proceeded to hone under the tutelage of a Josef Karma on the Isle of Man, Douglas.

Savile claimed that Karma had offered to teach him about hypnosis, and they worked together for a few weeks before he started to hypnotise people under his tutor’s guidance. He said he found that he could do it quite easily.

‘So when I came back to Leeds after the six weeks, I found…’ he paused for a moment to relight his cigar, ‘a hypnotherapy clinic. They’d get patients in and let me hypnotise them and try to sort them out, and I learned various techniques. I don’t use it very often.’

He cackled and looked straight out to sea.” [In Plain Sight, Dan Davies, Loc 3197]

“I wanted to know about the mysterious powers of hypnotism he claimed to possess. The pitch and cadence of his voice, a voice that became the standard-issue impersonation for just about every British citizen born before 1980, occasionally induced a drowsiness in me, especially if subjected to it for long stretches at a time. After a few hours listening to his pulsing drone – and occasionally being scolded for interjecting with a question or request for clarification – I invariably found myself needing a break….

So when did he first realise he had powers? “I was in the Isle of Man doing a disc jockey thing in Douglas, ‘ he replied. ‘And in the hotel I was staying at, because I was the star DJ at the time, the waitress came across and said – er – er what’s his name now?’ He groped for the name of the hypnotist he claimed had recognised his powers. I knew the name and reminded him: it was Josef Karma.

Josef Karma. Yes, he was doing a one-man show at the Royal. So Josef comes over to my table. And I said to him, “that’s a fascinating game is that.” And he said, “You can do what I can’t do Jim.” And I said, “What’s that?” “You can do mass hypnosis. You probably don’t know you’re doing it but you know the effect you’ve got on people. You know what you can do but you don’t know how it comes or what it’s called. You can do mass hypnosis and I can’t.” ‘

Now consider the 'British Invasion', mass hypnosis?
