Music superstar Kid Rock performed a thunderous version of his classic “American Bad A**” at the Republican National Convention Thursday night. Rock updated some lyrics to reference GOP nominee Donald Trump.

Rock riled up the crowd by quoting Trump’s famous “Fight! Fight!” rally cry after the failed assassination attempt on his life in Butler, PA less than one week ago.

“Say fight, fight,” he added. “Say fight, fight. Say Trump, Trump.”

Rock wrapped his performance by calling Trump the “most patriotic, badass on earth.”
