Among her many friendships, Diana's relationship with Elton John was probably the best-known of them all. The pair were close friends from the time they met in 1981, according to Harper's Bazaar, and he was introduced to her sons as well. Although they briefly fell out over the inclusion of photos of Diana in a book, they reconciled in the Summer of 1997, after their mutual friend Gianni Versace died.
John's most enduring legacy of his friendship with the princess is "Goodbye, England's Rose," the rewrite of "Candle in the Wind" that he performed specifically for Diana's funeral and reportedly refused to perform again unless asked by her sons. He has remained close to both Princes William and Harry, attending William's 2011 wedding as a guest and performing "Your Song" at Prince Harry's reception luncheon.
