The documentary consists of three episodes each focusing on a different era of British folk music. Episode 1 - 'Ballads and Blues' - explores the revival era, episode 2 - 'Folk Roots, New Routes' - travels through the acid-folk and folk-rock of the 60s and early 70s and episode 3 - 'Between the Wars' - looks at the post punk years.
As with all these documentaries there's something for the novice and the acolyte alike. Even with music I'm not much of a fan of - and I have to include the vast majority of British folk music in there, hence the facetious comment about willowy hats back there - I do love to watch passionate people talk about their work and their love of the music and there's plenrty of that on offer here.
