Here John talks about his French life, writing and the best way to get a good deal at the next vide-grenier you attend.
Craig McGinty: What were the reasons behind your move to France?
John Dummer: My wife Helen and I moved to France with our three Staffordshire Bull Terriers and two cats in the eighties. I had been managing a rock band, the Screaming Blue Messiahs for three years and have to admit I was burnt out from all the craziness of touring in the US.
