indisguise I understand your point. The people in GBNC must have broken down the cost and added up to the audiences. The hall rental 600$ sound Engineer 200$ appliance Rantal 200$ Entertaining and feeding the tour group Travelling costs Profit... etc The cost actually adds up and the base line is the artist have come here to MAKE MONEY by entertaining you. they must have some basis to determine the price otherwise they would not want turn away lots of audiences. Choice is yours.
