Sting's 60th birthday party was one for the ages. Bruce Springsteen, Billy Joel, Lady Gaga, Stevie Wonder, Herbie Hancock and Iron Man himself (Robert Downey, Jr.) all joined the former Police bassist in recognizing the 25th anniversary of his solo career, launched on 1985's The Dream of the Blue Turtles.
Robert Downey, Jr. – who was gearing up to promote the second installment of his Sherlock Holmes reboot, A Game of Shadows – took a breather from the road to serenade the sold-out crowd at Manhattan's Beacon Theatre (home of the famed Allman Brothers residency) with a rockin' rendition of "Driven to Tears," from the Police's 1980 album Zenyatta Mondatta. Professional footage of their performance – shot in 2011 but only just hitting the web now – went viral late last night, and it's clear why: Downey, Jr. is a shoo-in for Sting, capable of mimicking Sting's riveting charisma exactly.
