I have to admit, this guy was my first hero before I had heard of Phil Lynott. The question of self-infliction I answered yes as it was due to the drugs and his lifestyle that lead to his poor health and ultimately his premature death.
But it was interesting to see how you, SMX, went from thinking of Freddie Mercury to Jim Morrison (as per the dates of death given).
