(CNN) Sir Elton John is saying goodbye to life on the road.

The music icon announced at a press event on Wednesday that his next world tour will be his last. The three-year tour will start in September, John told CNN's Anderson Cooper in a sit-down chat that was live-streamed around the world.

"I've been touring since I was 17 with various bands," John said. "I thought the time is right to say thank you to all my fans and say goodbye."

John said his priorities changed when he and his husband, David Furnish, had children.

"We had children and had changed our lives and in 2015 we sat down with their school schedule and we said I'm going to miss too much of this," he told Cooper.
