The concert will be over when Madonna says it is over. During her Rebel Heart Tour stop in Glasgow, the venue operators decided it was time to go and turned the power off. Guess what Madonna did next? See the video below.

Madonna on Paris terrorists: “They want to silence us. We won’t let them.” 

After all if terrorists aren't going to get in Madonna's way, why would a lack of electricity bother her? She considered canceling her November concert in Stockholm a day after the Islamic State attacks in Paris but pressed on.

“I feel torn. Why am I up here dancing and having fun when people are crying over the loss of their loved ones?” she said then. “However, that is exactly what these people want to do. They want to shut us up. They want to silence us. We won’t let them. We will never let them.”

So, cut the power if you like. Madonna will drop the mic and exit when she decides it's time.
