I just happen to have two copies of Picking Sooty Blackberries.

One is the personal autographed copy I was given by the surviving members of Cockersdale who were the driving force in ensuring the book saw the light of day. This was a thank you from Val, John and Graham for the foreword I had provided when John gave me an ultimatum I couldn't refuse.
The other is a bought copy.
Neither is for sale as they say on the Antiques Roadshow!

I also have a signed copy of the Prospect Providence LP of Keith's songs which I was instrumental in making possible - right person at right place at right time.
Also not for sale.
