On the biggest night out of the year, Iain Stirling - stand-up comedian, presenter of Dog Ate My Homework (CBBC) and the voice of Love Island - explores the history of Saturday nights out across Scotland since the 1950s.
He attempts the jive, the twist and even a little roller disco. He hears from those who were there at the Fountainbridge Palais, Edinburgh, the Locarno in Glasgow and Robbies in Dundee at their wildest. He speaks to the man who brought The Beatles to Bridge of Allan. He hears the real story of the rave scene.
He savours a 1970s evening, complete with a cheese and pineapple hedgehog, and he enjoys archive footage of some of Scotland's most enjoyable nights out.
