Bruno Mars slays at pre-Super Bowl concert

HOUSTON — The Super Bowl halftime show is on Sunday. Someone maybe ought to tell Bruno Mars that. The pop singer was in grade A form at a pre-Super Bowl show on Friday night, performing a top notch concert that matched the energy he showed when he hit the stage at halftime last year and in 2014. He worked Club Nomadic in Houston like a veteran: He danced slickly on one song, sang impressively on another, and played guitar throughout his 90-minute set.
