Hi Carl,
Never thought I would read about London Golf Club! Back in the early-mid '90s, my wife and I were able to play PART of one of the two courses there. We were three couples, one of which was Ron Kirby and wife. Ron had worked for the Nicklaus Design Group in Europe and had helped design/build both courses. We were playing the course which Ron insisted had the most design imput from him personally when a cart came up to us and informed us we would have to leave the course immediately. Seemed the owner/builder, a Mr Nagahara, wanted to play and didn't want anybody else on his course at the same time. OK, we left.
Next day we attended the Grand Opening Match between Jack, Seve and Tony Jacklin over the Heritage 18. I think the other course was called the International. Both were very much American style golf courses built over some pretty flat land somewhere out near Kent.
This made me start a search and, yes, I still have the Grand Opening "Programme"
