Actually, I'm pretty sure the person was joking, and everyone in the audience laughed as soon as the person shouted that. Can't say for sure, but I think Peter was amused at the person's timing for that one from the expression on his face for the person's timing. He was introducing Rhythm of the Heat.

To a certain degree, I think it's becoming a joke between Peter and his fans, more then the person shouting it being serious. :-]

Mostly as by now, most people going to his New Blood concert already know he's not playing many of the Big Time pop songs.
