At Highgate School, Moss developed a fascination for sports, especially boxing, but he did not want a professional sporting career. It was also at Highgate that he formed his first band, Pig Williams, along with his friend Nick Feldman (who would later become a member and co-founder of Wang Chung). Together they performed at several school events. After finishing high school, Jon held various jobs, including working at his father's clothing store, as a cake salesman and as a sound engineer at Marquee Studios. In spite of regarding a college education as a waste of time, he briefly considered the idea of studying Greek at the University of Cambridge.
