Maroon 5’s Super Bowl set ended with a boom — loud enough to send part of the ceiling crashing down in a Royal Oak bar.

A Birmingham woman suffered facial injuries Sunday night when a tile was shaken loose and fell during the band's pyro-packed performance of “Moves Like Jagger."

Kathy Vargo and a friend were at Royal Oak's Rock on 3rd establishment. They said they'd already been impressed by the venue's high-end audio system, loud enough to clearly hear the TV commentators over the bar noise.

"We're sitting in a booth watching (Maroon 5's halftime) show, the big ending comes and — boom, boom, boom — a ceiling tile hits me in the head," said Vargo. "As far as I knew, the whole place had exploded.

"It was heavy. It hit hard. The biggest thing was all the blood after that," she said. "There was dust everywhere, and people were freaking out."

Vargo sustained a gash in her left eyelid and was treated at Beaumont Hospital, receiving 13 stitches. Another guest was struck in the back by a tile but was unharmed.

Rock on 3rd owner John Corradi said the pair of four-square-foot tiles fell as the halftime set came to a climax. He called it "a fluke accident" and said he and his staff quickly attended to the injured patron.

"We got ice, gauze, bandages," he said. "I've been in this business a long time, and we've got a great reputation in Royal Oak and with the city. We did everything we could."

Grosse Pointe police officer J.P. Cormier was the second victim of falling tile, and he initially feared a bomb had been detonated.

"It was the last song. (Adam Levine) took his shirt off and all the fireworks started going," Cormier said. "And then, boom. One tile hit me in the back and fell into the booth. But one came down right on her."

Vargo and Cormier said they'd been digging Maroon 5's halftime set before the crash.

"Adam Levine literally brought the house down in Royal Oak," Vargo said.
