To those paying close attention, Tuesday night's reunion, while unexpected, should come as little surprise -- it's been widely reported that Grohl recently employed his old bassist's services for a track which will appear on the new, forthcoming Foo Fighters album. That album, incidentally, is also being produced by Butch Vig, who masterminded Nirvana's 1991 seminal breakthrough, 'Nevermind.'
While the Foo Fighters used the intimate show to showcase some of their new material, the short Nirvana segment saw Novoselic and Smear join Grohl on stage to perform 'Marigold' -- originally a b-side for the hit single 'Heart Shaped Box,' it's the only original composition that Grohl contributed to Nirvana. While many celebrities were allegedly spotted in the audience, we're guessing that Courtney Love was not one of them.
