"I was at Cambridge with other would-be Situationists like Paul Sieveking and I was a member of the Kim Philby Dining Club which I think had some people from the Angry Brigade involved. We all wanted to to destroy the system but didn't know how. We knew about Strasbourg and the Situationist tactics of creative plagiarism and basing change on desire. The Situationists offered, I thought then and I still think now, the only future revolution I could imagine or want" (quoted in Andrew Hussey, The Game of War: The Life and Death of Guy Debord, 2001).
The Kim Philby Dining Club did indeed include among its members John Barker and Jim Greenfield, later jailed for their part in the Angry Brigade bombing campaign of the early 1970s. According to Gordon Carr in his book 'The Angry Brigade' (1975) the Club was named after the ex-Cambridge Russian spy in around 1968 'by a group of Cambridge Situationists in honour of the man they regarded as having done more than any other in recent times to undermine and embarrass the Establishment'.
Also came across On The Passage Of A Few Persons Through A Rather Brief Period Of Time by John McCready, another article specifically on the SI and Factory Records. He uncovers some other connections, reminding us that it was actually Rob Gretton (among other things New Order's manager) who came up with the Hacienda as a name for the Factory nightclub in Manchester, inspired by reading a copy of Christopher Gray's Leaving the Twentieth Century - a collection of Situationist International texts given to him by Tony Wilson. He also notes that there was a Kim Philby bar in the Hacienda, that A Certain Ratio name checked a Situ/Surrealist hero on 'Do The Du(casse)' and gets Peter Saville (designer of iconic Factory sleeves) enthusing about the 'two cowboys' image in the situationist 'Return of the Durutti Column' comic strip.
