Here's what we've heard:
There are some spooky occurrences (think ghosts, spirits, etc.) going on in Greenwich Theatre. They must have been going on for some time because the London Paranormal Society is carrying out a seance there this Saturday, June 30 from 9pm-4am. They will be looking into the Grey Lady myth.
What's so exciting is that anyone can join in for 55 pounds (wonder if they'll split the money with the spirit who shows up!) Who knows? but if you're willing to give it a go, then you can sign up at the society's website.
The Greenwich Gazette has tried to contact both the Greenwich Theatre and the London Paranormal Society to inquire about the events and to get you more juicy details, but so far neither have responded to the emails. Will keep you posted though.
