My husband suggests we round up a small 'band' of performers (a few hundred should do it, although more would certainly be welcome!) to go perform live just outside, say DCMS (the Department of Culture, Media and Sport), (apparently demonstrations are banned within a certain distance of Westminster/Parliament, so that's probably not a practical choice of location) -- or maybe in front of Buckingham Palace, or in a Royal park, or just outside a major city's town hall? Presumably none of these places are licensed to have live gigs, and therefore the DCMS ministers, or the Royal family, or someone inconveniently embarrassing -- would be in violation of this asinine reg -- and subject to prosecution, fine, etc.

Probably requires a bit more in the way of research to be sure, though (like, would everyone simply be arrested for trespassing or somesuch rather than violating licensing regs?) -- anybody out there know a bit more about such things?

If I thought it could really work, I'd be there like a shot...
