Gosh, that's a shame -- I wasn't even aware of that Scott Adamson story. I knew they had resurfaced somewhat in the late 1990s, but I never heard "the end of the story," so to speak.
Adamson had a long-standing problem with alcoholism, going back to when he was with The Skids in the late 70's/early 80's. From everything I'd heard, he stayed clean & sober throughout most of the 1990's. He moved to Nashville, TN sometime in the late 1990's and was here in the US when September 11 happened. Apparently, that affected him deeply, and he began drinking again. He was displaying erratic behavior throughout that fall (he was a no-show for a scheduled concert, for example). He finally disappeared sometime in December, and they found he had hung himself in his hotel room in Hawaii.
