First, the big news: The surviving members of Nirvana recently got together and performed 'Smells Like Teen Spirit.' Now, the catch: Only one other person was around to hear them.

Dave Grohl recently invited his former Nirvana bandmate Krist Novoselic to play a couple of songs at a Foo Fighters gig in California, and a little magic happened during their pre-show rehearsal.

Grohl and Novoselic, along with current Foo Fighters member and one-time Nirvana touring guitarist Pat Smear, were rehearsing the songs for that night's set when Novoselic suggested they "run through some oldies."

"Krist is on bass. Pat's on guitar. I'm on drums," explains Grohl to The Observer. "Me and Pat look at each other. I mean, that's something I've never considered before. I was, like, 'OK?'"

Grohl continues, "Krist says, 'F--- it, let's do 'Smells Like Teen Spirit,' and Pat starts playing, and we kick into it. I haven't played that drum beat in 17 years. It was crazy. It was like … a ghost. It was heavy."

Grohl says only one other person, aside from the three musicians, witnessed the historic event. "Our studio manager was the only guy there," Grohl, "and when we'd finished he was like, 'Hey, you should record that.'"

One thing the three rockers didn't do was try to step into the shoes of late Nirvana frontman Kurt Cobain. "Nobody sang," reveals Grohl.

It was recently announced that a 20th anniversary edition of Nirvana's landmark album 'Nevermind' will hit stores Sept. 19. Click here to read all about the deluxe release.
