Katy Perry was one of the performers at King Charles III’s coronation concert ceremony. She opened up with her 2013 single “Roar,” ushered in by a gigantic firework lion, and then talked a little bit about her experience at yesterday’s coronation. Then she sang her Teenage Dream hit “Firework.” Let’s appreciate the irony of Perry singing a song with the lyrics “Just own the night/ Like the Fourth Of July” at the King’s coronation.
