Paul Simon, the 83-year-old musician known for his work as a solo artist and as part of the duo Simon & Garfunkel, canceled two concerts scheduled for June 28 and 29, 2025, at Philadelphia's Academy of Music due to chronic and intense back pain. The pain had become unmanageable, necessitating a minor surgical procedure. Following the cancellations, Simon underwent successful back surgery to address the severe condition. As a result, he has postponed additional shows while recovering. Refunds were offered to fans for the canceled Philadelphia performances.
