I was fortunate enough to see Chris and the rest of the aces back in the early 70's at Hyde road when I lived in the UK. I remember him well, especially the polka dots and the side'ies. I have some great b/w photo's of him that I bought at the track back then, they bring back great memories every time I look at them. He will always be remembered as one of the great aces in my mind, along with Mauger, Wilkinson, Sjosten, Collins and Broadbelt.
My deepest sympathy and condolences go out to his family.
