Go to the main page of either ISIHAC or The News Quiz (not The Now Show yet, unfortunately). There’s a link to an ‘AND’ filter. It searches the database for shows which have all of the pieces of information you add. As you add more information (e.g. the chairman, the panellists, the producer, etc.) so the list of shows it could be gets smaller, till eventually you’re left with hopefully just one that it can be.
