Now then, now then guys and dolls, who was the very first DJ in the UK and the first dude to wear tracksuits and big jewellery? Jimmy Saville OBE, of course. Jimmy is credited with inventing DJing when he spun his records in a village hall long before discos were invented. He wore shiny tracksuits and chunky gold jewellery before Ali G was even born. BBC reporter of all things weird, Louis Theroux, spent a week with Jimmy. Catch 'When Louis met Jimmy' (BBC2 9.30pm) on Thursday and get some style tips from the man whose flamboyant dress sense hasn't changed for over 30 years.
