Simon and Garfunkel sing, again

Dusting the cobwebs off their friendship, the folk-rock duo Paul Simon and Art Garfunkel announced Tuesday they were reuniting for a concert tour of North America this fall.

Shows begin Oct. 18 at the Palace at Auburn Hills, outside Detroit, and include Nov. 14 at the Arrowhead Pond of Anaheim and Nov. 17 at Staples Center in L.A. Tickets for both go on sale Sept. 22.

The 1960s favorites, who last recorded together in 1975, have sold more than 40 million albums in the United States. They’re calling the tour “Old Friends,” but the men, both 61, have had a contentious relationship until the ice broke earlier this year when they performed “The Sound of Silence” together at the Grammy Awards.

“It’s family, the two of us,” Garfunkel said. “Our moms know each other. They’re still alive. There has been a deep, buried affection for the last decade or so, and it was the Grammys that forced it out of burial.”
