Prince Williamis celebratingKing Charlesas the coronation festivities continue.

One day after King Charles, 74, and Queen Camilla, 75, were crowned at Westminster Abbey, the royal family gathered on the grounds of Windsor Castle on Sunday for theCoronation Concert. While an eclectic lineup of performers took the stage — includingLionel Richie,Katy PerryandAndrea Bocelli— the Prince of Wales, 40, also had a turn at the microphone for a special speech dedicated to his father.

Standing before a cheering crowd and thanking those behind the epic evening, the heir to the throne began, “I want to say a few words about my father and why I believe this weekend is so important. But don’t worry, unlike Lionel, I won’t go on all night long,” he joked in a nod to the “All Night Long” hitmaker, whose performance preceded his remarks.

“As my grandmother said when she was crowned, ‘Coronations are a declaration of our hopes for the future,’ " Prince William said, quotingQueen Elizabeth’s coronation speech from 1953. “And I know she’s up there, fondly keeping an eye on us. She would be a proud mother.”

Turning back to his father’s crowning, the prince continued, “For all that celebrations are magnificent, at the heart of the pageantry is a simple message. Service,” the Princes of Wales said. “My father’s first words on entering Westminster Abbey yesterday were a pledge of service. It was a pledge to continue to serve. Because for over 50 years, in every corner of the U.K, across the Commonwealth and around the world, he has dedicated himself to serve others, both current and future generations, and those whose memory must not be neglected.”

“Take the natural world. He warned us of the risks to our planet’s health long before it was an everyday issue,” William said, pointing to his father’s lifelong passion for conservation and the environment. “Or the Prince’s Trust. It has supported over a million young people, many from disadvantaged backgrounds, to realize their ambitions,” he continued, referencing Charles' namesake charity, established 1976.

“And, perhaps most importantly of all, my father has always understood that people of all faiths, all backgrounds, and all communities, deserve to be celebrated and supported,” the Prince of Wales added, emphasizing his father’s interest in and dedication to interfaith relations. “Pa, we are all so proud of you.”

“I also want to express my pride and gratitude for the millions of people who serve, in the forces, in classrooms, hospital wards and local communities,” William continued. “I wish I could mention you all. Your service inspires us, and tonight we celebrate you too.”

“I commit myself to serve you all. King, Country and Commonwealth,” he concluded. “God Save the King.”
