The story goes that there was a pane of glass with his name scratched in it and countless other names from that era. When the pub was turned into a brasserie, a lot of old stuff was dumped in a cellar. When the new landlord took over, he found the pane of glass amongst the stuff.
Someone then told him about the old story about Nelson's name and, lo and behold, and by divine coincidence on the very day he was running a Trafalgar Day special in his pub, up turns the pane of glass!
Spooky, eh?
