King Charles III coronation recap: The biggest moments

William, the heir to the throne, honored his father with a speech recognizing Charles' decades of service to others and to the planet.

William was met by loud cheers when he took the stage in front of Windsor Castle.

He honored his father's service, noting the pledge of service Charles gave at Saturday's coronation as well as the "over 50 years of service" he devoted before becoming king.

"We're all so proud of you," William said.

The royal ended his speech by saying, "I commit myself to serve you all, king, country and Commonwealth. God Save the King."

Music star Lionel Richie performed his hit songs Sunday night in front of royalty.

Richie played the piano and sang his hit song "Easy (Like Sunday Morning)" in front of a crowd of thousands, including Charles, Camilla, William and Kate.

He then got up and danced as he sang another hit song, "All Night Long (All Night)."

In addition to performing at the coronation concert, Richie also attended Saturday's coronation service at Westminster Abbey.

Prince Louis, who stole the show at Saturday's coronation, is not in attendance at the Sunday night coronation concert at Windsor Castle.

William and Kate are attending the concert with their two oldest children, Prince George, 9, and Princess Charlotte, 8.

Louis has become a crowd favorite thanks to his lively personality at recent royal events, from last year's Platinum Jubilee to Saturday's coronation of his grandfather.

Charles and his wife Camilla were greeted with big cheers Sunday as they arrived at the coronation concert in Windsor, England.

The newly-crowned king and queen got a rousing three cheers from the crowd as they stood in the royal box.

Seated with Charles and Camilla are members of the royal family, including Prince William and Kate, the Princess of Wales, and their two oldest children.

Actor Hugh Bonneville, the concert's host, opened the show by recognizing Charles' "lifelong passion for the arts." Bonneville got a quick laugh from Charles when he referred to the king as "the artist formerly known as prince."
