For all those fans hoping Malcom Young is going to return to AC/DC. It's final. He's not coming back. Fans who have been hoping the 61-year-old's absence was temporary will have to get used to the fact that it's permanent, and that his nephew Stevie, who appears on their upcoming album, is the man they'll see on the road in his place. "The Aussie giants have remained tight-lipped about Young's condition in order to protect his privacy. The only official statement announced he'd be "taking a break" while his colleagues worked on the follow-up to 2008's Black Ice. No one has commented on speculation that he's suffered a stroke, has cancer or is fighting Alzheimer's disease." Frontman Brian Johnson said in June that "We're aiming to be back on the road before the end of the year.".
