You may recognize this young man from Petty's "Into the Great Wide Open" music video. A grown up Johnny Depp joined the band for the better part of the show's last half, playing guitar cooly with a cigarette in his mouth. By far, Depp's appearance caused the most excitement as he casually sauntered onstage in his fashionable pirate-style garb, guitar in hand.
Har Mar Superstar started the night off with the Tom Petty classic "Don't Do Me Like That."
New York punk rocker Jesse Malin lunged around onstage and in the audience during his rendition of Petty's "Wreck Me."

Producer and recording artist Butch Walker celebrated his 43rd birthday onstage with his Venice Vintage Motorcycle Club pals in the audience, all in cuts, tearing through "Breakdown" with a committed force.
Comedian Sarah Silverman showed impressive vocal chops singing "Don't Come Around Here No More" in her instantly recognizable nasally cartoonish voice, ranting over the song's end such nonsense as, "Don't come here no more… And I don't appreciate it… Don't stop by… Fuck you… Because I don't need your shit anymore."
The hard hitting Black Keys drummer Pat Carney leant a hand pounding out a rhythm, appropriately, on Petty's "Anything That's Rock and Roll."
Ke$ha jumped onstage to sing a stoney verse in Petty's "Mary Jane's Last Dance."
