Andrew Marr remembers David Hockney | The New Society

A Bradford boy who became one of the most famous artists in the world. A gay man who made desire visible decades before it was safe to do so. A painter who took on the iPhone and the iPad and bent new technology to the oldest of artistic impulses. What do the pools, hedgerows and iPad drawings add up to? Andrew Marr and the New Statesman's art critic Michael Prodger join Tanjil Rashid to discuss the life and legacy of David Hockney, who passed away last week.
