It seems to me, Mike, that your comments only enhance what Brian and I have been saying about the way PB presented himself differently in different circumstances. I often saw him in the early days in the company of Bob Copper and he was always on his best behaviour then as well.
About my writing, I don't even think that he really disliked it. It was just as Brian describes. "Right, the gig is over and what I need now to relax is a good argument." He was a truly complex person.
