In part one of a brand new three-part series, Iain Macwhirter examines the social, cultural and political changes that have taken Scotland from being at the heart of the union in 1945 to today, preparing for a referendum on independence. Elaine C Smith, Donald Findlay QC, George Galloway MP, Jim Sillars, Margo MacDonald MSP, actor Bill Paterson, Tam Dalyell and author William McIlvanney are some of those who recall the huge upheaval that Scotland underwent in the 50s and 60s.
