Did you ever learn to play it once you'd found the tabs? I kinda wish I'd bothered to learn to play an instrument so I could do stuff like that, haha.
BK was quite a big part of my childhood, too! I spent several months waiting for it after it was released because Amazon messed up my order, it drove me crazy. It also got me into forums and stuff. Thinking about the trio boss fights still makes me cringe, though...
