Whilst reading about notable people who share my surname, I discovered this bizarre article on the Highgate Vampire media sensation of the 1970s.

> There was more publicity about Farrant and Manchester when rumours spread that they would meet in a "magicians' duel" on Parliament Hill on Friday 13 April 1973, which never occurred.

Highgate Cemetary is where Karl Marx is buried, as well as many other famous people. You have to pay to get in, and Hampstead is a pretty rich area high up in London.

What I'm saying is, the people who could have access to the cemetery at that point in the night are probably the rich "rock and roll" teens who lived there (Oasis at one point lived on Steele's Road).
