This is the awkward moment that Carrie Underwood’s performance of the National Anthem at President Donald Trump’s inauguration was hampered by tech issues.
The country music superstar was forced to perform acapella after the backing track failed to play during the ceremony on Monday morning.
It is not yet clear what caused the technical issue, but the singer pressed on and was joined by members of the crowd gathered in the rotunda.
The Grammy-winning superstar won singing competition show "American Idol" in 2005.
Artists like Beyonce and Celine Dion asked Trump to stop using their songs in the lead up to the 2024 election. Neil Young and Guns N' Roses are among the performers who had asked him to stop using their music ahead of and after the 2016 election.
But Mr Trump has garnered the support of rapper Waka Flocka Flame and country singers Kid Rock and Billy Ray Cyrus, the father of Miley Cyrus, among others.
Mr Trump, who overcame impeachments, criminal indictments and a pair of assassination attempts to win another term in the White House, was sworn in Monday as the 47th US president.
His swearing-in ceremony was moved indoors due to intense cold and began at noon ET. Festivities started earlier when Trump arrived for service at St John's Episcopal Church.
Declaring that government faces a "crisis of trust," Mr Trump said in his inaugural address that under his administration "our sovereignty will be reclaimed. Our safety will be restored. The scales of justice will be rebalanced."
Mr Trump claimed "a mandate to completely and totally reverse a horrible betrayal," promising to "give the people back their faith, their wealth, their democracy and indeed their freedom."
"From this moment on," he added, "America's decline is over."
