SMELLS LIKE JON STEWART: Sirius XM said on Thursday that surviving Nirvana members Krist Novoselic and Dave Grohl, along with producer Butch Vig, will sit for a two-hour interview with host Jon Stewart on Sept. 24, the 20th anniversary of Nevermind. You can hear it live on Lithium (naturally). Audience members for the Q&A will be chosen via an online contest. (8/26a)
