I came across one more J. G. Ballard item in my archives.
Raw Feed (2009): “The Autobiography of J.G.B.”, J. G. Ballard, 2009.
A sort of combination of a Ballard story and autobiography. In something out of one of his stories, the protagonist, B, wakes up to find everyone gone. Leaving his Shepperton home (where Ballard lived), B roams as far south as Brighton and Dover and eventually goes to France. He finds nothing, stockpiles food, guns, and gasoline and proceeds to get down to his work uninterrupted.
