Thanks for this Oxon. I had almost forgotten him, shame he will tend to be defined as a result of the Dennis Wise incident (I loved someone saying that Wise should have the "Biggest C" award).
I Googled CD and came up with a very interesting Scottish article from last weekend. Obviously very bright as he studied Civil Engineering at University and highly regarded by those like Eggs who had dealings with him. One to watch, along with Potter from Brighton who has a similar unconventional background.
