Inside the Spectacular Coronation Concert with Royals and Celebrities.

Elton John turned down an invitation to perform at King Charles III's Coronation Concert due to his ongoing Farewell Yellow Brick Road tour. However, his complicated friendship with Princess Diana may have also played a role in his decision. Despite Elton's absence, the concert will feature performances from Katy Perry, Lionel Richie, Andrea Bocelli, and others, with Tom Cruise and Nicole Scherzinger also slated for a segment.
