@PartyScanCTG The Nirvana version of the song was leaked to The Stranger, a Seattle newspaper, in 1998, presumably by someone in the band, so that she'd quit claiming she wrote it. They leaked about 15-30 seconds of the song and refused to release the source.
i prefer kurt's home acoustic tape of this to the recorded one. and hole's is incredible too. just to set the record straight, kurt gave the song to courtney who rewrote the lyrics for her version. she didn't steal it. and her lyrics are original.
Hole's version of 'Old Age' is a b-side on their 'Beautiful Son' single (which has a picture of Kurt Cobain as a child on the cover).
The section before 'Old Age' starts on the video above (from 1:12) also turns up on a Hole record - before 'Credit in the Straight World' on 'Live Through This'.
