Carrie Underwood was slated to perform “America the Beautiful” with the United States Naval Academy Glee Club and the Armed Forces Chorus before Trump took the Oath of Office. However, her performance didn’t go as planned. She sang after the Oath of Office and without accompaniment.

Due to last-minute changes to the inauguration, Underwood was going to sing to a recorded backing track. However, the track failed. Instead of scrapping the performance, the country superstar proved to the world how well she works under pressure and delivered a stunning acapella rendition of the patriotic standard.

In the clip above, Underwood says, “If you know the words, help me out here,” inviting everyone in attendance to sing with her. Then, she led a room full of some of the most powerful people in the United States in song.

Fans React to Carrie Underwood’s Stunning Performance

The memorable moment came after many fans believed that Carrie Underwood’s performance was cut from the inauguration schedule. This made her stunning performance that much more memorable for everyone in attendance and those watching from home. Several fans took to social media to applaud the American Idol judge for keeping her cool under pressure.

“Carrie Underwood just pulled the best audible ever, Wow!” one fan tweeted after seeing the performance.

“Goosebumps listening to Carrie Underwood sing as well as the room full of people! That was pretty special to watch,” another added.

“I enjoyed Carrie’s performance more without the background music—it was nice hearing everyone else sing along with her,” one fan tweeted. Another called Underwood a “national treasure” after seeing her performance.

Last week, Underwood spoke to People about her performance at the inauguration. “I am humbled to answer the call at a time when we must all come together in the spirit of unity and looking to the future,” she told the publication. There is no way she could have known that she would bring a room full of people including former president Biden and former vice president Harris, together to sing the praises of the United States. In that moment, the “Before He Cheats” singer proved that music can bring people from all walks of life together, even if only for a brief and fleeting moment.
