 An early interest in music took him into the record industry, by which time he had realised that he had no future as a performer.

 After completing this course with Honours, he was immediately offered a place as a part-time adult education lecturer, an occupation he found extremely rewarding.
 By this time he was also working on the extensive manuscript journals of the 18th-century English amateur composer, John Marsh, an undertaking that ultimately resulted in his edited version being published in the United States in 1998.
 His most recent book is a study of catch and glee culture in 18th-century England.
