“We met for breakfast and even before our eggs arrived, he had knocked back two double tequilas and a beer. That was eight in the morning.
“I remember him saying that he woke up one day and felt he was surrounded by spirits. His sister said, ‘Yeah, Jim Beam, Jack Daniel’s and Johnnie f****** Walker.’
“He didn’t have too long to live and I think he knew it. He had a tragic aura. He died at 27 but, to be honest, he was really gone by about 25.”
