Just listened to the Peggy Seeger programme on the wireless. There wasn't much folk but it was steeped in folk revival, the stance, the sound, the politics. She came close to regret when describing her and MacColl attitude's to folk as uncompromising, perhaps arrogant (if I paraphrased her correctly without listening again).
The more I read and listen the less idea I have what what Folk is, or even if it exists, while becoming increasingly certain about the mores of the revival cult.
