Can we get an update on current Busking Laws?

If you know the requirements for a certain city or spot, add it to the list. (Don't forget to add the country, if it's not obvious).
Example:
   Abcville, Calif. - License required, apply at city hall. $150 annual fee. No amplification.
   Deftown, Somerset, UK - No specific laws.
   ...etc.
   
We'll assume that these basics apply, unless otherwise posted:
- Never block the sidewalk/pavement.
- Never block a shop entrance and try not to obstruct a shop display window.
- If asked to move by the police, Do it. Politely, quickly, pleasantly.

It would also be really nice if people added suggestions for good places to play in different towns, such as "Try the corner of Main Street & Townhall Road", or "avoid the front of Such-and-Such shop, the owner hates buskers".
