Bruce Springsteen and John Mellencamp teamed up on December 9th at Manhattan's Beacon Theatre for Sting and wife Trudie Styler's all-star concert to benefit The Rainforest Fund. reported the highlight of the '80s-based show was Mellencamp's rendition of "Jack & Diane," followed by "The Boss" joining him for "Pink Houses" and Mellencamp returning the favor during "Glory Days," before Springsteen played "Dancing In The Dark."

Sting performed recent touring-mate Peter Gabriel's "Sledgehammer," with Debbie Harry tackling Blondie's "Call Me" and "Rapture" -- with special guest DMC. Bob Geldof performed his Boomtown Rats classic "I Don't Like Mondays" and a rendition of Elvis Costello's legendary cover of Nick Lowe's "(What's So Funny ‘Bout) Peace, Love & Understanding." James Taylor was on hand to sing "Your Smiling Face," and "Up On The Roof."

The Eurythmics' Annie Lennox and Dave Stewart played a three-song reunion set consisting of "Sweet Dreams (Are Made Of This)," "Would I Lie To You," and "Here Comes The Rain Again." Also performing were Ricky Martin, Shaggy, and actor Robert Downey, Jr., who joined the ensemble for a show closing finale of Journey's "Don't Stop Believin'."

Sting has always felt that it was his duty as a celebrity to lend a voice to people and causes that might otherwise be denied: "I've always demanded citizens' rights, but that means also that you have to have citizens' responsibilities. And as a citizen of the world, if you have a platform to say something useful, than you, you should use that. And so, I've tried to do that. I've succeeded in some things that I tried to do -- failed in others; but I think it was always a worthwhile thing to -- as a citizen -- to do."
