Eddie Vedder, the lead singer of rock band Pearl Jam, joined String and Peter Gabriel during a KeyArena concert July 21 in Seattle.
"It seems Vedder was returning a favor to Sting who joined Pearl Jam onstage at New York's Madison Square Garden in May, when they performed the Police's 'Driven to Tears,'" Rolling Stone reporter Daniel Kreps wrote. "In addition to playing 'Tears' again, Vedder stuck around – Sting and Gabriel sometimes trade off songs mid-set during their anything-goes trek – to help out Gabriel by taking lead on the second verse of 'Red Rain.'"
