Simon & Garfunkel cancel tour

Billboard reports the duo Simon and Garfunkel announced on their website that their upcoming summer tour is on hold indefinitely.

Art Garfunkel is continuing to recover from a vocal paresis, a serious condition that affects the vocal chords. He is expected to make a full recovery but the duo is not rescheduling any dates just yet.

Simon & Garfunkel were supposed to play a number of shows in Canada and the United States in April. Those shows were postponed until July and now have been put on ice completely.

Art Garfunkel sends his apologies to fans: "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."

Last year, Simon & Garfunkel toured Australia, New Zealand and Japan. They appeared alongside Bruce Springsteen, U2 and Eric Clapton at the 25th anniversary concert for the Rock and Roll Hall of Fame held at Madison Square Garden in New York.

Before that, the last time the North American public saw Simon & Garfunkel live was in 2003.
