Sad news. Got to know Don fairly well in the late 60s/ early seventies. I Ibooked him several times at my Surbiton and Kingston Folkclub and also at some Open-air Concerts in The South London Parks. He never quibbled about the fee - he used to say "Whatever you can afford Derek" He always gave an entertaining performance. In recent years whilst he was busking around the South Coast he used to send me messages and I finally caught up with him again a few years ago whilst he was busking in Dartmouth ! He was still doing the Old routine and enjpying the Busking. Good memories of a modest, talented, likeable guy !
