At Oundle, Dickinson was picked on and routinely bullied by the older boys of Sidney House, the boarding house that he belonged to, which he described as "like systematic torture" and meant that he became an outsider. His interests at Oundle were often military; he co-founded the school wargames society with Mike Jordan, and he rose to a position of some power in the school's cadet force, with which he was allowed to handle live ammunition, which he used to create explosions as booby-traps. Oundle was where Dickinson became attracted to hard rock, after hearing Deep Purple's "Child in Time" being played in another student's room. As a result, the first album he ever bought was Deep Purple's "In Rock", which created his interest in rock music. After "In Rock", he went on to buy Black Sabbath's debut, Jethro Tull's "Aqualung" and "Tarkus" by Emerson, Lake & Palmer. Every term, a band would play at the school, the first of these which Dickinson saw was called Wild Turkey, featuring former Jethro Tull bassist Glenn Cornick. After that, he saw Van der Graaf Generator and Arthur Brown.
