The rumors began last week when people started putting two and two together—The Rolling Stones rehearsing in L.A., for their Zip Code tour, kicking off Sunday at San Diego's Petco Park, and the odd notice that Shakey Graves’ May 20 booking at the Fonda was being moved to the Belasco Theater due to an issue with “logistics.” May 20 is here, and we can confirm that the Stones will indeed get up-close and personal with a few hundred lucky fans this evening in the intimate confines of the Fonda.

This surprise warm-up show for the upcoming tour also syncs up with UMe’s deluxe reissue of the band’s 1971 masterpiece Sticky Fingers, and the Stones are expected to draw heavily from that LP in their setlist.

In taking over the venue on Hollywood Blvd., the band is following in the footsteps of Tom Petty & the Heartbreakers, who did four nights at the Fonda in June 2013, drawing packed crowds and the dreaded fire marshals.

You’ll recall that the Stones did a surprise show at the Echoplex two years ago, with tickets priced at $20 and doled out by a lottery system, while unsuspecting fans formed a line around the block at the El Rey on the day of the show thinking it was first come, first served (see photo). It’ll be interesting to see how the tickets are allocated in this instance.

The LA Weekly unlocked the mystery in a speculative story posted on Monday, noting that its “spies” had spotted Keith Richards and Ronnie Wood at Musso & Frank and Mick Jagger at La Poubelle on Franklin. The story also noted that the old-timers will do their first-ever Twitter Q&A this afternoon. Use the hashtag #AskTheStones to submit questions and track the band's answers.
