Episode 8: The Culture Show at the Edinburgh Festival - Part 2

Sue Perkins presents a second helping of The Culture Show from the Edinburgh Festival and meets author Kirsty Gunn and music legend Nile Rodgers. Also featured tonight, the 25th anniversary of So You Think You're Funny, the Edinburgh comedy competition which has uncovered stars from Dylan Moran to Peter Kay. Artists including David Hockney, Paul Gaugin and Sir Peter Blake swap paint for wool in an exhibition of contemporary tapestries, and we take a look at Speed of Light - a spectacular mass participatory event in which walkers and endurance runners ascend Arthur's Seat and illuminate the iconic mountain.
