Sarah Smith takes a light-hearted look at the early careers of the big players in this year's Referendum debate and lifts the lid on the not-so-public bits of Alex Salmond, Nicola Sturgeon, Alistair Carmichael, Johann Lamont and Alistair Darling's past lives. In Referendum Connections , she'll reveal where their careers have crossed and connected, not just with each other but with a multitude of public figures in Scottish public life and drags up some early TV appearances they'd wish had stayed hidden in the BBC vaults.
