At 8pm EST on September 24th, the 20th anniversary of the release of Nirvana’s Nevermind, Jon Stewart will be sitting down with Dave Grohl, Krist Novoselic, and Nevermind producer Butch Vig for a two-hour Q&A to be broadcast on Sirius XM channel 34. They’ll talk about Nirvana and also, I assume, how lame Fox News is.
