Paul McCartney will perform the first ever concert at Safeco Field tonight and word on the street is that he’s bringing some notable local guests with him to mark the occasion.

I received a text from a reliable source told me that “all surviving members of Nirvana are in town today.” This probably isn’t a coincidence since Sir Paul and Pat, Dave and Krist famously recorded together for this year’s Sound City soundtrack.

I’m still waiting to get official word from representatives of McCartney, Grohl and Novoselic, and I will update this post when/if I hear back from them, but the chances of this being merely a rumor are very, very slim.

Brief update: Krist and Pat are in town as per Krist’s Twitter account and local writer Matt Driscoll confirmed a Dave Grohl sighting outside of the Alexis hotel. More proof of a Sirvana song at Safeco happening tonight. Also, EMP Museum posted this picture of Grohl at the museum today.
