The woman who pulled the plug on The Boss rather than give him ten more minutes speaks:
I can understand the disappointment of fans when the Springsteen and McCartney duo came to a rather un rock'n'roll-like end. However the licensing rules are ultimately not there to kill the party, but to go some way to discharge the legal responsibility we also have to consider.
We make up some rules and, by jingo, we're going to enforce those rules - to the second - regardless of how many folk's pleasure we spoil as a result. Those licensing rules really are, absolutely and specifically, design to 'kill the party' and that's just what they did. To no-one's benefit.
