one noticeable song left off the setlist was "Teen Spirit". In an interview a few weeks after that show, he admitted that he forgot how to play the solo.
Stone: Along with everything else that went wrong onstage tonight, you left without playing "Smells Like Teen Spirit." Why?
Cobain: That would have been the icing on the cake [smiles grimly]. That would have made everything twice as worse.I don't even remember the guitar solo on "Teen Spirit." It would take me five minutes to sit in the catering room and learn the solo. But I'm not interested in that kind of stuff. I don't know if that's so lazy that I don't care anymore or what. I still like playing "Teen Spirit," but it's almost an embarrassment to play it.
