It may not have been a great game until after the lights went out and came back up, but the Super Bowl showdown Sunday night created quite a few memorable moments on the field and off, even before kickoff.

There were powerful performances, including a much buzzed-about halftime show by superstar Beyonce.

But there was also a lack of electricity in the stadium and in some of the commercials.

And San Francisco 49ers fans are sure to get emotional over that last play they ran on offense, when two players met in the end zone and, despite interference, the referee did not call a penalty.

Here are the five moments you can expect your coworkers to talk about Monday morning.

Grrrl Power

The men may have duked it out during the game, but when it came to the non-football entertainment at the Superdome, women ruled the day.

First up was Jennifer Hudson with a stirring rendition of "America the Beautiful." The choir backing her was composed of students from Sandy Hook Elementary, the Connecticut school where 20 students and six school staff were shot dead in December.

Players on the sidelines and fans in the stands wiped away tears.

"Our wish is to demonstrate to America and the world that 'We are Sandy Hook and We Choose Love,'" the choir said in a statement.

Next, Alicia Keys belted out the "Star-Spangled Banner" as the children, in white polo shirts with green ribbons pinned to them, stood with their hands on their hearts.

"It's football. But I just cried," tweeted actor Brian Baumgartner about the Sandy Hook performance.

The big show, however, came once the 49ers and the Baltimore Ravens got through the first half.

Welcome, Beyonce.

For 12 minutes, she rocked the stage clad in above-the-knee black stiletto boots and a leather minidress.

Powered by an all-female backing band, there was little doubt Beyonce sang live -- unlike during President Barack Obama's inauguration last month where she admitted singing along with a prerecorded track.

And as if that wasn't enough girl power for the night, Beyonce was joined by her Destiny's Child bandmates, Kelly Rowland and Michelle Williams.

"Watching the #SuperBowl with family & friends. @Beyonce was phenomenal! I am so proud of her! -mo," tweeted none other than the first lady of the United States, Michelle Obama.

She wasn't the only one. Beyonce's performance generated 5.5 million tweets!

Lack of power

For the first two quarters, the Ravens seemed unstoppable, steamrolling the 49ers and building a 28-6 lead.

But then, half the lights in the Superdome went black.

Monitoring equipment sensed an abnormality in the building's electrical system and cut power to some sectors to isolate the issue. Power utility Entergy said the problem was a "customer issue."

The NFL released a statement saying it was "investigating." The power company said it was not to blame and that electricity in the rest of the city was fine.

The outage left players, coaches and fans to wait, wait and wait some more.
