Copyright and its relationship with popular music is one of the most disputed issues amongst music and copyright scholars. While some have accused copyright of being blind (or deaf) to the particularities of popular music, others have defended its significance within the industry. This article contributes to this debate by tracing the networks of connections between lawyers, musicians, and clerks that emerged in a formative period in British pop music (the Sixties). It considers how their collaborative efforts and strategies to present evidence in copyright infringement trials were articulated in an attempt to influence music copyright infringement tests in Britain. By highlighting the concrete geographical and temporal contexts from which these networks emerged and their particular contingencies, the article also casts a new light on the impact of the legal profession on copyright, showing a practice‐oriented and historically situated way of observing differences between French and British copyright systems.
