PLYMOUTH businesses have been reminded they need two copyright licences if they want to play recorded music – even if it is "incidental" music.

John King comments:
Oh no it doesn't.

The incidental exemption does not of course apply only to recorded music. Currently exempt from additional entertainment licensing, as a performance of incidental live music, traditional folk music sessions, which can take place without playing any music which is under copyright - do not of course require such licenses.

And even those sessions which may include the occasional tune which is under copyright, would require such a small fee, as to make the exercise to calculate it, from PRS etc. a waste of time.
