Madonna, queen, sis... stop going on late.  The Palladium in London put the house lights up and pulled the curtain down on her during her final number. She had an argument with the theater's management, then came back out and carried on with no microphone to finish "I Rise."  Madonna even admitted the theater threatened to pull this kind of a stunt earlier in the week, and they followed through.  Girl just start on time. She even tried to spin it as some kind of empowering thing.
