I've seen him in the Starbucks at our local Sainsburys a few times. This, observers of the celeb spotting thread in OT may be interested to know, is the same one in which I have repeatedly seen Ian Beale from Eastenders and that mental Jo Cameron woman from the Apprentice a few years ago (last saw her last week, she's smartened herself up a bit).
Anyway, my favourite spotting of Mr Dublin was the last time, when i was behind him in the Starbucks queue. He ordered his drink and the girl asked him for his name for the cup. "Dion", he said. "Sorry?" she said. "Dion" he replied.
I don't really know why, but it just made me laugh.
