Way back someone asked about busking in Cambridge UK. Yep it's still a license free city but there are a lot of other buskers so you have to be very good or very different to make any money. There is now a group called Cambuskers, they have a facebook page, who organise buskers for some of the Cambridge festivals but not all. On festival days it'll be the other buskers and busking organisers who'll be asking you to move from Cambridge Council agreed festival busking sites, the police don't get involved. But if you are asked to shift it will be done in the polite, well mannered way that is Cambridge.
