Thanks Nick. Those interviews seem to corroborate the video interviews I've seen George tell the same story in various documentaries. The meteorological and historical data on typhoon Dot on the day George met Bruce, plus the fact George says he was with Bruce for three or four days, works out to be close to, if not exactly, July 17th.
So I think George was with Bruce for four days, from Tuesday to Friday. He then stayed in HK for the funeral.
