The only one I could find was this, and its a short piece by one of the people convicted of the bombings. I'm sure I've seen something else - I had two good friends killed in the Tavern and I know there was something written that brought the whole thing back. Sorry I haven't got time to have a look and remind myself how to do a blue clickie!
