I'm sure a staph member will know, but I was under the impression that ticket prices are set by the venue after they find out how much the band want to be paid for the gig. For example.
Band wants 40 big ones.
Venue holds 1,500 punters.
26.66 per ticket
15.00 Seths boat payment
10.00 Twangirls days pa appointments
12.00 Thatguys new piercing
01.00 employee salaries
64.66 per ticket!
No?
