Paul Cole of the U.K.'s Sunday Mercury reports that former GUNS N' ROSES and current VELVET REVOLVER guitarist Slash faced a medical crisis of his own while appearing at Michael Jackson's 40th birthday concert at Madison Square Garden.Slash — whose real name is Saul Hudson — reveals that it was his first gig after having a major heart operation. "Years of drinking had swollen my heart to the point of bursting," he recalls. "It reached the point where the doctors gave me between six days and six weeks to live. They installed a defibrillator to keep my heart from stopping and keep it beating at a steady rate. After the operation I began therapy and miraculously my heart started to heal. I was out of circulation for four months before I picked up a guitar. It was the darkest period of my life — but in 2001 I agreed to play at Michael's birthday celebration. “This was my first gig since the operation so I was looking forward to it. It certainly turned out to be memorable." Read the entire report from Sunday Mercury.
