Singer Sir Elton John has said coming out gay did not negatively affect his career.

The 65-year-old Sir Elton makes the revelation in a two-part interview with TODAY host Matt Lauer to be aired Tuesday and Wednesday, July 17 and 18.

The conversation revolves around Sir Elton's upcoming memoir, Love is the Cure: On Life, Loss and the End of AIDS, sales of which will benefit the Elton John AIDS Foundation.

“I wasted such a big part of my life, when this [AIDS] epidemic was beginning to happen in the early 1980s. And I was a drug addict and self-absorbed,” he told Lauer at his home outside London. “You know, I was having people die right, left and center around me, friends. And yet, I didn't stop the life that I had, which is the terrible thing about addiction. It's that – you know, it's that bad of a disease.”

“I'm making up for it,” he added. “There is so much more to be done.”

On coming out, he said: “In America, people burned my records for a second and radio stations didn't play me. It didn't have any effect like the Dixie Chicks had when they made the anti-Iraq statements and their career was ruined. So by me saying gay in the 1970s – it didn't have a big effect on me whatsoever.”

Sir Elton and his partner, filmmaker David Furnish, are raising 1-year-old Zachary.

“I'd love to have more children,” Sir Elton said. “And I want him to have a brother or a sister to go to school with. And so that he can have someone to play with.”
