In a recent interview for The Times, the legendary singer-songwriter revealed that he has been suffering from sudden hearing loss. "Quite suddenly, I lost most of the hearing in my left ear, and nobody has an explanation for it. So, everything became more difficult.” Paul Simon / The Times. While Simon expected the ear would eventually "repair itself", the condition hasn't improved. Accordingly, he has doubts he will perform live again - also due to the fact that he is tired of singing some of his older tracks.
