Adam Smyth, lecturer in English at Balliol College, Oxford, and books journalist James Kidd discuss literature from curious and creative angles. This week's theme: Literature and Hair. Adam and James are joined by historian Alex von Tunzelmann to ask, which writers had great hair? Has hair inspired great writing? What does hair symbolise? And is hair-dressing an art? Featuring Alexander Pope, John Milton, Rapunzel, Vidal Sassoon, Little Women and - probably - Melvyn Bragg. For more information visit litbits.co.uk.
