Attree writes as the editor at large for the satirical magazine "The Chap". His feature interviews have included Leslie Phillips, Sir Patrick Moore, Brian Blessed, Alan Moore and Jilly Cooper, while his ongoing column "The Pentagram of Atters" contains information regarding the supernatural. Attree is a campaigner and activist within the "Chap movement". In his book "London Calling: A Countercultural History of London since 1945", Barry Miles recalls how Attree (along with two colleagues) climbed to the top of a Rachel Whiteread art installation as part of a "Tate Modern Protest".
