Now that I think more about it, I must have got the track from a P2P service / network. But I had a bajillion Nirvana bootlegs when I was an adolescent. Thinking of the misnaming phenomenon, the hidden track (from Nevermind) was alternately named either "I Hate Myself and I Want to Die" or "I Love Myself and I Want to Live" on those live performances (after Cobain's suicide). 1990s and no or limited internet, so it was whatever someone decided.
Thanks for surfacing the track so readers can hear it! It's one of my favorites.
