Don't kid yourself... Sting didn't do it for free, he got paid... the corporate sponsors paid his fee which allowed them to give away tickets. Rarely does a performer play for free!
The point was that everyone is complaining about prices, and whether Sting gets paid or not isnt the point, it is what you the consumer has to pay. Please don’t tell me now that on top of listees not wanting to pay the current prices, that there is also a stipulation that Sting isnt allowed to make money either ?...
