PS I almost forgot, the pub in question was The Black Swan in Effingham, Surrey, a key landmark in horror film history as it was the interior of The Slaughtered Lamb pub which Jack and David had the misfortune to stumble into in, of course, An American Werewolf in London.
It's now almost unrecognisable unfortunately (or perhaps fortunately come to think of it) and there were no weird goings-on to be reported. Although at one point, I could have sworn my Guinness magically refilled itself...
Also rather aptly, the nearby hotel I stayed in was called The Talbot Inn.
Here's some professionally taken photographs:
