NIRVANA - Unknown Jam (with vocals)

Some bootleggers call this song ’Ivy League’, ’The Son’ Etc. I don’t really know what it is called - and I think only people in the Nirvana camp know the original title. All credit goes to the fan who mashed up Jam at Lang and the SB recording og the 1993 San Diego show. If you did this, please write me, so I can give you credit by name!
