Again - busking and street performing are different, do not merge 

Regardless of the size of the crowd that walkby acts draw, the nature of the perrormance is inherently different, and it is the nature of the performance that is defined in this wikipedia entry, not the size of the crowd.

I admin the street performance page and have kept it completely clear of spammers for the duration that I have been involved, so this is neither a reason to merge or a problem for the entry on street performer.

By reading the street performer entry, it is obvious why there should be a separate entry to that of busking, there is really no need to merge for reasons of clarity of practicality, and do to so would be destructive to both entries.
