Williams' Heart Op Successful

Robin Williams fans, take heart: The funnyman’s surgery to replace an aortic valve went “extremely well,” according to a cardiothoracic surgeon at the Cleveland Clinic, where the operation was performed today. “A couple hours after surgery, he was entertaining the medical team and making us all laugh,” said the surgeon. Health problems had forced Williams to postpone his one-man show, Weapons of Self-Destruction, although he is expected to resume the 80-city tour this fall. The actor said through a spokesman: “I’m thinking the next leg of the tour will be Weapons of Self-Destruction and Reconstruction!”
