Elton John Will Be Performing at The Royal Wedding John is reportedly performing at the ceremony on May 19, after rescheduling two shows in Las Vegas set for this weekend. The singer and pianist famously performed “Candle in the Wind” 21 years ago at Princess Diana’s funeral. He was very close with Lady Di, and the two worked together to raise money for AIDS research and awareness. The wedding rehearsal takes place on Thursday and will see the royal couple take a 25-minute carriage ride through
St. George’s Chapel.
