The Simon & Garfunkel website is reporting that the legendary folk duo are postponing their Old Friends reunion tour indefinitely due to vocal stress affecting Art Garfunkel. The tour was launched at the New Orleans Jazz Festival, where the stress on Garfunkel's voice was evident. That week, the remaining dates were pushed back to July before the latest news. "I do feel bad about disrupting so many people's plans but, as I continue to mend, I can't yet bring my 'A Game' to a tour, and I would not perform for you with anything less," Garfunkel said in a statement posted on the duo's official website.

Doctors say that Garfunkel will recover completely, but have given no clear timetable.
