Paul Simon, the 83-year-old singer-songwriter, has canceled two concerts scheduled for June 28 and 29 at Philadelphia's Academy of Music due to chronic and intense back pain. The condition has become unmanageable, prompting Simon to undergo a minor surgical procedure to address the issue. The cancellations were announced by his team, emphasizing the urgency of the medical intervention required. The decision affects his weekend performances in Philadelphia, with no immediate information on rescheduling.
