Perry Farrell, Jakob Dylan, Tom Petty & the Heartbreakers guitarist Mike Campbell, Regina Spektor and The Whigs frontman Parker Gispert all made surprise appearances at New York’s Bowery Ballroom during last night’s Stones Fest. Part of the Best Fest series, the all-star event benefited Sweet Relief and The Sweet Relief Musicians Fund.

Like the benefit’s sister events Dylan Fest and Petty Fest, an eclectic mix of actors, musicians and other East Village New York denizens performed a few songs with Rolling Stone contributing editor Austin Scagg’s Cabin Down Below Band. Last night’s musical cast included Norah Jones, The Black Keys drummer Patrick Carney, Jason Isbell, Butch Walker, Delta Spirit, Cory Chisel & Adriel Denae, Johnny T, Adam Green, Jesse Malin, Alberta Cross’ Petter Ericson Stakee, Ruby Amanfu, Nicole Atkins, The Mooney Suzuki’s Sammy James Jr., Danny Clinch & The Tangiers Blues Band, The Uptown Horns and many others.

Near the end of the show, a slew of guests took the stage. First, Gispert joined Carney and members of The Cabin Down Below Band for a take on “The Last Time.” (Along with the Uptown Horns, Carney was one of the few acts on last night’s bill to actually perform with the Rolling Stones.) Then, both Regina Spektor and Campbell—enjoying a night off from the Heartbreakers’ Beacon Theatre run—both emerged for a cover of “Jumpin’ Jack Flash.” This is the first time Campbell has appeared at a Best Fest event, though Tom Petty is the inspiration for another one of the benefit series’ events.

The parade of guests continued. Jakob Dylan sat in on “Loving Cup” and “Ruby Tuesday” while Perry Farrell joined Atkins and The Cabin Down Below Band for ““Sympathy for the Devil.” After proudly proclaiming his Queens, NY roots, Farrell also brought out his wife to sing with him on “Time is on My Side.”

Stones Fest returns to the Bowery Ballroom tonight.
