The case quoted in the radio programme was different from the Kwik-Fit case. It concerned one man who worked alone in a lab to which the public were not admitted - it was specifically NOT a public area.
What the PRS alleged in their reply was that "in public" means anywhere outside a private home, which is an astonishing definition of "public", and one I would have thought oopen to challenge in the courts.

I'm also still struggling with the logistics facing an employer whose employees listen, in different rooms, buildings or areas, to different radio stations, or who switch stations between programmes. How, precisely, are the royalities to be worked out on these broadcasts, and by whom?
