The Chicks are singing the national anthem, as the prime-time programming kicks off.

It's been more than 20 years after the group went from country music darlings to pariahs after speaking out against then-President George W. Bush at a concert in the run-up to the U.S. invasion of Iraq.

"Just so you know, we're ashamed the president of the United States is from Texas," singer Natalie Maines told fans in London in March 2003.

The country group sang "The Star-Spangled Banner" as the prime-time programming kicks off.

Maines later apologized, saying her remark was "disrespectful." But country radio stations across the country yanked the trio from playlists, while some protesters resorted to publicly trashing their CDs to demonstrate against the singers' perceived lack of patriotism.

The group changed their named from The Dixie Chicks in June 2020, during the height of the Black Lives Matter protests. They also released their first album in 14 years -- "Gaslighter" -- that year.
