Diz's version was the very first one I heard - at the Redan pub on the corner of Westbourne Grove and Queensway - around 1970. He lived upstairs at the time and our band played there every Thursday. He used to sit in quite regularly. When I'd moved down to Sussex in '76, I accompanied him now and then when he ventured down for a folk club gig. The prune song was a regular event - plus the song about breaking a lady's tambourine!
