At the present time, a traditional music session in Peterborough, with unpaid customers, is prevented, and the licensee is facing prosecution, as this is considered as Public Entertainment and illegal without a licence and a fee.

However, I am at the moment 'watching' a live TV broadcast from a public building in London, where before a paying (and clapping) live audience, and a live TV audience a chap is conducting a real Post Mortem/Autopsy, for 'entertainment'.
