I have mixed feelings about this too Don. The principle of auditioning buskers is not so bad in itself, because it is an attempt to draw the line between people who can entertain and earn their money and those who would not get a gig in their local pub and are simply out to beg for money. The problem is, you can't really audition for the way in which a good busking show works. The crowd pulling, interplay, build up of the show and even the bottling routines are an integral part of a good show. A good musician, juggler etc is not not automatically a good street performer.
