(Classic Rock) Paul Simon has hinted that he could retire after a farewell tour of Europe, suggesting he's "coming towards the end." The 74-year-old has been performing since he was 13 - rising to fame as part of Simon & Garfunkel in the 60s.

But he says he's found it difficult to keep up with the physical demands of touring and often needs 15 hours of sleep between shows. He tells New York Times: "Showbiz doesn't hold any interest for me. None. It's an act of courage to let go. I am going to see what happens if I let go.

"Then I'm going to see, who am I? Or am I just this person that was defined by what I did? And if that's gone, if you have to make up yourself, who are you?"

Simon says he plans to travel for a year with his composer wife Edie Brickell after scheduling a European farewell tour this autumn. Read more here.
