Who is performing at King Charles III’s coronation concert?

Several artists will perform at a coronation concert Sunday night in honor of King Charles III. Some of the main acts include:

  • Andrea Bocelli and Sir Bryn Terfel: While most performers have been tightlipped about what they are singing at the big event, Bocelli has said Charles and Camilla requested that he and Terfel perform a duet of “You’ll Never Walk Alone,” a song he told People magazine is “a true tribute to solidarity.”
  • Take That: The group will be reuniting for the first time since 2019 for the coronation, per Marie Claire.

  • Katy Perry: “American Idol” judge Katy Perry is also skipping out on the show to perform at the coronation concert. Perry told Extra that it’s an “honor” to perform at the concert — and that she’s looking forward to staying at Windsor Castle.
