In February 2009, Simon and Garfunkel reunited for three songs during Simon's two-night engagement at New York's Beacon Theatre. This led to a reunion tour of Asia and Australia in June and July 2009. On October 29, 2009, they performed five songs at the 25th Anniversary Rock and Roll Hall of Fame Concert at Madison Square Garden. Their headlining set at the 2010 New Orleans Jazz and Heritage Festival was difficult for Garfunkel, who had vocal problems. "I was terrible, and crazy nervous. I leaned on Paul Simon and the affection of the crowd," he told "Rolling Stone" several years later. Garfunkel was diagnosed with vocal cord paresis, and the remaining tour dates were cancelled. His manager, John Scher, informed Simon's camp that Garfunkel would be ready within a year, which did not happen, damaging relations between the two. Simon continued to publicly wish Garfunkel better health and praised his "angelic" voice. Garfunkel regained his vocal strength over the course of the next four years, performing shows in a Harlem theater and to underground audiences.
