I was sad to read about this just now. I met Simon a few times over the years - he was excellent company and actually first introduced me to Chave (with the 85), now I come to think of it.
Indeed on that note, I recall later arranging a 88-91 Chave/La Chapelle dinner, 7 or 8 years ago, to which he brought the 90 Chave and I think also the 78 Blanc as a surprise… but he fell fast asleep halfway through the main flight, yet was most unperturbed upon awakening - for these were wines he knew all too well and if anything he was just disappointed to have missed the banter with friends!
