Hi,
re: PY joining in 1962 or 1963, I raised this question in conversation with Peter Holmes in December 2007, and Peter was quite certain that he himself joined CG in January 1963, and that he had met Paul at the blacksmith's the previous summer.
I sometimes can't remember which year I joined / left several companies 10 or 20+ years ago, unless I check my CV...
So, I'm not sure Paul would in 1978, at which point he was 74.
