Today Professor John Cook is recognised as the preeminent academic authority on the life and work of Dennis Potter. In 1990 he was a Phd student researching for his thesis on Potter - later to be published as the monograph Dennis Potter: A Life on Screen (1994). The then young John secured an interview with Potter at the London office of his agent Judy Daish. The recording of that interview, on basic equipment of the time was recorded on a c90 cassette tape. John himself describes the sound quality on these original recordings as "very murky, full of background noise and tape hiss". Now though, thanks to digital tools the sound has been restored and John has started to release them to mark what would have been Dennis Potter's 90th year. Thank you John for sharing this audio treasure trove!
