I'm coming to this late, having just heard. I met Sean many times, mainly in the Volunteer at Sidmouth (he was one of the people from the Swindon club who always dropped into the festival for a day or two on their way to the Dartmoor weekend), and always enjoyed his company and his singing; we danced together a couple of times too. He was a lovely man, and I'm sorry to hear that he's fallen victim to this terrible disease.
