Singing legend Sir Elton John previously opened up on his mortality and the future of his career admitting that he did not think that he had long left. The documentary Elton John: Never Too Late delves into the iconic musician's illustrious career. The documentary, directed by RJ Cutler and Sir Elton's husband David Furnish, sees the 78-year-old reflect on his mortality and his legacy.

In one scene, he ponders: "I wonder what is going to happen to all of this stuff when I finish? This is the latter time of my life. I don’t know how much time I have left. And you think about that more when you get to my age. You think about life and death. You think: Well, I just want to be where I want to be now."

Speaking about the future of his career, Sir Elton added: "I don’t have to work after this tour. I will be working doing records and putting radio shows together, and doing other things, but travelling takes so much out of you."

"It is very tiring. I am used to it and I am a veteran at it... but this is where you start to think about mortality". His children, Zachary, 13, and Elijah, 11, are also aware of their father's age: "They worry about my mortality because they know how old I am."

Sir Elton expressed his desire to be with his family for as long as possible, saying: "Not so much David, but me, they love their Daddy so they want me to be around forever. I would love to be around forever.

"I want to see them have children, and get married, but I don’t think I am going to be around for that, who knows, you never know. So that’s why I want to make the best of my time while I am around....time together is so wonderful and so precious."

The singer also opened up on his sobriety, speaking at the BFI London Film Festival last year. He said: “I come off stage for the last time in America, and Dodger Stadium again, where I have the most wonderful life. No sadness, just happiness, family, children, husband, friends, sobriety. It was a hell of a difference.

“And it’s shown in two pieces – what can happen to people who aren’t really, I wasn’t prepared for the success I had, I loved it, but the back end of it, or the bad side of it, was that all I had was music, and there was nothing else and no foundation whatsoever. So they captured it brilliantly, and I really didn’t have much to do with it. I let them get on with it."
