It's about Brian Jones, one of the Rolling Stones

Since there's nothing else for them to do, Sussex Police are going to reopen the investigation into the death of Brian Jones:

"It's too early to comment at this time as to what the outcome might be," the Sussex duty inspector said, reading a statement over the telephone. Police did not give further details.

Yes, there's only been forty years for this to be poked about in. Far too early for any sort of answer to start to present itself.

The duty inspector said that, in particular, the force were keen to talk to all of Mr. Jones' laughing friends to establish where they were at the bitter end.
