1973 or 4, the trainee teacher came in and held up this album cover, and asked us young teenagers what we thought of it. There was no response. Against the grain, I raised my hand and said 'Flattering'. He laughed, and it felt like he and I were the only people in the room who had any idea what was going on. He asked us to write something, and next lesson his comment came back - 'Use the space - paper is cheap', or something along those lines. He was probably 20 or so.
