If Jim Morrison had lived

Let's imagine that Jim Morrison hadn't died at the age of 27. Okay, he'd probably have died at 28, or 29, or 30. But what if - somehow - he had lived. What would he look like today? Like Kurt Russell, reckon some scientists who have produced an computer-aged image of him. They've only done the face, though, and haven't gone as far as to stick him in a studio recording an album with Rick Rubin, or halfway down the Sunday bill at Glastonbury.
