The largest and most encouraged Buskering going on has to be the touristy Ghirardelli Square in San Francisco.These street musicians surely make 20K plus during the height of the tourist season.They likely have night gigs as well. Some ten tears ago they had the infamous "Human Jukebox".This musician had decorated a large appliance box to look like a juke box with slots for green stuff money with song selections at each slot. When money went into the selected slot, the little curtain would rise and this bearded trumpeteer would wide eye appear and like a mechanical robot commence playing your favorite selection. Street entertainment at its best. The area was full of a wide variety of acys.Their musicians must obtain a permit before just any one can go out and busker. Another novilty idea I stumbled on and found to be most worthwhile was a workshop at a festaval, "How To Busker" conducted by traveling musicians Jem Moore and Ariane Lydon. They had some challenging ideas on how to busker anywhere when money got tight. Most cities don,t have laws against buskering, instead have laws pertaining to vagrantcy and panhandling. Musicians are providing a service for donations would be their defence. But they also advised when confronted by the authorities to gather your best money and move on. Tourist gigs are at best since the flow of new audiences are always changing. A real nice subject to ponder on.. Thanks Jack mostly folk
