The question over whether Rolling Stones founding guitarist Brian Jones drowned or was murdered 50 years ago this month is the subject of a new Netflix documentary. Who Killed Christopher Robin? is based on a 1994 book by investigative journalist Terry Rawlings, titled in reference to Brian's Cotchford Farm having once been the home of Winnie the Pooh author AA Milne. The doc contains a 2009 interview with Brian's road manager, Tom Keylock, who says Brian was out of his mind on drugs the night he was found floating his in pool.
