A new political era is about to begin in the United States as President-elect Donald Trump takes his seat in the White House.

In a few days, Trump will take his oath as the new U.S president, and his inaugural team has been fully engaged to make the event monumental. Rumor has it that they are having a hard time getting high-caliber performers to join the merriment. After all, the inauguration is not just about political speeches.

It was previously reported that singers Elton John, David Foster, Charlotte Church, Rebecca Ferguson, Moby and Ice-T had publicly announced their refusal to take part.

Nevertheless, there were performers who confirmed their attendance.

Jackie Evancho, the 16-year-old "America's Got Talent" alum, will sing the "Star-Spangled Banner." Other artists who have confirmed their involvement are 3 Doors Down, The Frontmen of Country, Big & Rich, and Lee Greenwood.

The Rockettes will deliver a dance show, while the Mormon Tabernacle Choir and the Talladega College Tornado Marching Band will also showcase their talents.

On the other hand, some of the performers had to defend their decision to join Trump's big day after their fans' adverse reaction in social media.

In his statement with Entertainment Weekly, country musician Toby Keith stated that his presence is not to endorse the President-elect.

"I don't apologize for performing for our country or military. I performed at events for previous presidents [George W.] Bush and [Barack] Obama and over 200 shows in Iraq and Afghanistan for the USO," Keith explained.

The Piano Guys, in their official website, released a statement addressing their acceptance of the invitation and apologizing to their followers who were upset over the decision. The group indicated that, like everyone else, they want what's best for the country. They stressed their idea of unity and respect to all women, religion, and race.

"We haven't changed our message. We haven't changed who we are, what we stand for, or what our music means and why we write it. We're still doing what we've always done — playing for anyone who will hear our musical message with the hope that it persuades its listeners to love others," The Piano Guys concluded their statement.
