I am no political renegade, but for anybody with even a tiny interest in music, this has to be detrimental.
I don't even live in London and I find this legislation horrendous.

"The 696 Form compels licensees who wish to hold live music events in
21 London Boroughs to report to the police the names, addresses, aliases and telephone numbers of performers, and most worryingly, the likely ethnicity of their audience. Failure to comply could result in fines or imprisonment. We believe this places unnecessary and frankly Orwellian powers in the hands of the Metropolitan Police, an institution which does not have the best record of racial fairness. The 696 form can only serve to deter the staging of live musical events - a positive form of activity in London and all cities - stifle free expression and quite possible penalise certain genres of music and ethnic audiences. It is an intrusion too far."
