Enduring a stern grilling by Orrin Hatch (R-Utah) and New York Democrat Charles Schumer, Azoff, seated next to LiveNation kingpin Michael Rapino, uttered a statement only a few outlets, including Nashville industry blog Coolfer, reported: “I would also like to get on the record that when people hear what Ticketmaster’s service charge is, Ticketmaster was set up as a system where they took the heat for everybody. Ticketmaster gets a minority percentage of that service charge. In that service charge are the credit-card fees, the rebates to the buildings, rebates sometimes to artists, sometimes rebates to promoters.”
