Music lovers are still in awe of Robert Downey Jr.’s performance at Sting’s 60th birthday celebration. “Ironman can sing – like that?!” is a typical response. Downey Jr. is humble about his friendship with Sting, as befits a superstar of his calibre. They first met when Downey was in his mid-twenties and was captivated by the idea that he was a talented songwriter, he explains. After a Sting performance, he tried to palm a demo cassette onto Sting in the stairway. Sting was surprised.

Robert Downey Jr. was recognised by Trudy Styler, Sting’s wife and a Less Than Zero enthusiast. She greeted the young actor, saying, “How kind of you to have come.” It wasn’t until 25 years later that Sting and Trudy mentioned it, telling Downey they had located the tape and asking if he wanted it returned. Downey deadpanned the idea that they could rewind the cassette and tape the case shut again if they listened to it. Thankfully, this did not stop Downey from attending Sting’s birthday fundraiser in 2011.
