He hasn’t aged well. He looks like he’s in his 90s.
He underwent surgery for a ruptured abdominal aortic aneurysm, and he remained in serious condition in the Intensive Care Unit (ICU). Lightfoot endured a six-week coma and a tracheotomy, and he underwent four surgical operations.[13] All of his remaining 2002 concert dates were canceled. More than three months after being taken to the McMaster Medical Center, Lightfoot was released in December to continue his recovery at home.
It's known as the Wreck of the Gordon Lightfoot.
I think he has MS. Not sure.
Given the lifestyle he had in the 1970s and 1980s it’s amazing he’s still alive. He would lock himself in a cabin up north, binge on amphetamines and write a couple of hundred songs, then after he crashed he’d pick twelve of them to record.
