Learning about the history of Plymouth Argyle during this process - especially 1973-76 when Paul played there - has been an absolute joy.
More than an hour on the phone with 94-year old Graham Little, the former club secretary, was fascinating and enlightening with stories aplenty.
And chatting about Paul to my fellow Scot Billy Rafferty allowed him to to reminisce about their lethal strike partnership at Home Park.
Just a reminder that the book will feature a section called 'Mariner Memories' with tales from supporters, so thanks to everyone who's already emailed their favourite memories of Paul at Plymouth to
book@paulmariner.com - there's still time for plenty more if possible.
All the best,
Mark
