As previously reported, Diana, Our Mother: Her Life and Legacy will air Monday, August 31, at 10 p.m. on HBO in America, and 9 p.m. in the UK on ITV.
In the documentary, friends, family and admirers speak about Princess Diana's charitable efforts, Elton among them.
The singer says that Diana’s efforts to promote HIV and AIDS awareness live on through her son.
“She had that incredible ability — which Harry knd of inherited — to make people feel at ease and make them feel that everything’s gonna be all right.
“I haven’t experienced many people in my life who have that ability, but she could walk into a room of people and make them feel as if everything was great.”
Diana was an early and very public campaigner for HIV and AIDS awareness and treatment.
It was considered to be a gay disease,” Elton says. “For someone who was within the Royal Family and who was a woman, and who was straight, to have someone care from the other side, was an incredible gift.”
