when we were 10 years old", when they were not working together. 1990–2018: Awards and final tour In 1990, Simon and Garfunkel were inducted into the Rock and Roll Hall of Fame. Garfunkel thanked Simon, calling him "the person who most enriched my life by putting those songs through me"; Simon responded, "Arthur and I agree about almost nothing. But it's true, I have enriched his life quite a bit." After performing three songs, the duo left without speaking. In August 1991, Simon staged his own concert in Central Park, released as a live album, Paul Simon's Concert in the Park, a few months later. He declined an offer from Garfunkel to perform with him at the park. By 1993, the relationship had thawed, and Simon invited Garfunkel on an international tour. Following a sold-out 21-date run at the Paramount Theater in New York and an appearance at that year's Bridge School Benefit in California, they toured the Far East. They became acrimonious again for the rest of the decade. Simon thanked Garfunkel at his 2001 induction into the Rock and Roll Hall of Fame as a solo artist: "I regret the ending of our friendship. I hope that some day before we die we will make peace with each other," adding after a pause, "No rush." In 2003, Simon and Garfunkel received a Lifetime Achievement Award at the 45th Annual Grammy Awards, for which the promoters convinced them to open with a performance of "The Sound of Silence". The performance was satisfying for both, and they planned a full-scale reunion tour. The Old Friends tour began in October 2003 and played to sold-out audiences across the United States for 40 dates until mid-December, earning an estimated $123 million. A second US leg commenced in June 2004, consisting of 20 cities. Following a 12-city run in Europe in 2004, they ended their nine-month tour with a free concert along Via dei Fori Imperiali, in front of the Colosseum in Rome, on July 31, 2004. It attracted 600,000 fans, more than their Concert in Central Park. In 2005, Simon and Garfunkel performed three songs for a Hurricane Katrina benefit concert in Madison Square Garden, including a performance with singer Aaron Neville. 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
