We were very sad to hear of Colin's passing. We will remember him as a good friend, who it was always a great pleasure to see and to spend time with. Graham spent many hours (I would love to be able to say they were exclusively "happy" hours, but.....) with Colin at international meetings in Vienna; far more enjoyable were the many times boredom got the better of us and we stood chatting outside over coffee or talking sport (or watching it) in one of Vienna's many cafes and restaurants. Colin's advice and expertise was immensely helpful to Graham ; but more importantly he was warm, friendly, kind and generous, and someone who clearly loved, and was proud of, his family. We will always remember Colin with great fondness, and send our very best wishes to all his family. Unfortunately we will be unable to attend his funeral, as we will be in New Zealand; but will be thinking of him and you all.
