Sorry Al but apart from "Colours", and that was mainly from the Bushburys in the 90s, I don't think that I have heard a Donovan song in a folk club during the fifty one years that I have frequented them. As for his influence on folk clubs, when I arrived on the scene back in 1966 the folk clubs of the North East were managing to scrape by without his help or influence (although I'm sure that they thanked him for his kind offer) and, as far as I know, they still are. The club that I have helped run for the last twenty six years in Nottingham has, unless I am most mistaken, never featured one of his songs during that time.
