Here is what I have on me at the moment that is in some what related to Nirvana. I decided I had to do a tribute of some sort. In about 1995 or 1996, a friend introduced me to Foo Fighters, and then I got into Nirvana. I wanted to find out why Cobain killed himself. And for about 3 years or so I was reading song lyrics, articles, getting books, magazines, pictures, all his albums & released singles. I have heaps of other stuff too, but now I have calmed a little, the answer to my old question is quite hard to explain in words. I'm not even sure if I understand it myself. But anyway, here's a badge thing I scanned.
Here's a decent picture of Kurt and his guitar. It's a little grainy, but it'll do.
This is also a pretty good one. I have seen similar shots to this one, as I am sure you have too. Most likely, if not, most definately taken when he recorded unplugged in New York.
Here's something you may appreciate. I formatted all the lyrics, put them in two columns. I mean all the lyrics Kurt wrote, well, all I could get my hands on anyway.
