Had no idea he was a heroin addict in the 90s. A complete surprise to me as that period was missed out of the excellent (4 hour) Peter Bogdanovich documentary, Runnin' Down A Dream.
Strange that having avoided that particular cliche for so long, he should succumb in his fifties. I guess that would go some way to explaining a weakened heart. Shame we've lost an artist that was still making good music. RIP
