In the forth of our Edinburgh specials, Christian and Jake talk to producer, writer and performer, John Lloyd. John started his career with BBC radio where he produced and co-wrote the original radio scripts for The Hitchhikers Guide to the Galaxy with Douglas Adams. He went to produce some of the most memorable comedy shows on British TV including Not the Nine O'Clock News, Blackadder and Spitting Image. He is also the producer of the comedy panel show QI which has now been running for nearly 10 years.
