The Cobalt Corfu Auction List, compiled by Sandra Bond, describes issue 10: "#10 particularly fascinating as it comprises John's account of the Aldermaston march which saw the founding of CND." John Brunner's song, The H-bomb's Thunder (1958), first written for this march, became the unofficial anthem of Campaign for Nuclear Disarmament, later released on the album, Songs Against the Bomb (Topic 12001).
During the 1950s, John Brunner wrote a regular column as the London correspondent for Lee Hoffman's folk fanzine Caravan, and contributed to Micheal Moorcock's folk fanzine Rambler, as well as various science fiction fanzines. He is best known for his science fiction novels, Stand On Zanzibar, The Sheep Look Up, and The Jagged Orbit.
