Singing great Paul Simon may soon be giving up music for good. “Showbiz doesn’t hold any interest for me, none,” Simon recently said in an interview with the New York Times.

His career began at the age of 13. Now at 74, he is said to need 15 hours of sleep to function efficiently.

“The other day, performing in Philadelphia, he looked out from the stage and was surprised to see four mountains on the horizon. When he put on his glasses, he realized the mountains were actually big white tents,” according to The New York Times.

His North American tour comes to an end on Friday in Forest Hills, Queens, where he grew up and went to school.

“It’s an act of courage to let go,” Simon said. “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 has a European tour scheduled for the fall, when he will turn 75. He then hopes to travel with his wife musician and composer Edie Brickell, if her work permits.

“I don’t have any fear of it,” Simon said.
