Newsnight - 23/01/2010

Jeremy Paxman presents a special programme to mark 30 years of Newsnight. What have been the big shifts in British politics and society over the last 30 years? Studio guests from the worlds of politics and culture debate, including Jarvis Cocker, Tracey Emin, Martin Amis and AS Byatt. Plus, 2-Tone ska band The Specials - who were number one for two weeks in 1980, shortly after Newsnight first went on air - play live. As well as a look behind the scenes at Newsnight, there are contributions from Kirsty Wark, Peter Snow and Martha Kearney, and a reminder of some of the classic moments from the show's three decades.
