I think Queen and Paul MUST have done a good job onstage with their setlist, because at the end of the concert you can hear people calling for an encore ("We want more! We want more!"). Otherwise why would people cheer back a terrible band?
Well, It maybe doesn´t depend so much on their performance. I would be really scared if they haven´t shouted anything. But I´m sure Queen+PR did a great job anyway!!
