Years ago, when I first heard of Roy Buchanan, it was from a chewed-up tape, a "collection" (analog warez?? ;-)) recorded from a friend's tapes & vinyl stuff... For years I searched for that exact rendition of "Hey, Joe" that had left me ecstatic, but the album was extremely rare and only recently, in 2004, I bought an (official) CD reissue of the '77 Buchanan classic "Live in Japan" - the original was from Polydor, Japan !!!
