Pearl Jam frontman Eddie Vedder and Rage Against the Machine guitarist Tom Morello, two alt-rock heroes with ties to the Windy City, sat in with Bruce Springsteen & the E-Street Band at Chicago’s Wrigley Field this past weekend. It was Springsteen’s first show at the historic Cubs stadium.

Partway through Springsteen’s set on Friday night, Morello—who grew up in the Chicago’s suburbs—emerged for “Death to My Hometown,” a song he recorded for the Boss’ new album Wrecking Ball. He returned a few numbers later for another Wrecking Ball cut, “Jack of All Trades.” As Morello left the stage, Vedder, who grew up outside Chicago in Evanston, IL, sang on the Springsteen classic “Atlantic City.”
Near the end of the set, Morello returned the for “The Ghost of Tom Joad,” “Badlands” and Wrecking Ball‘s “Land of Hope and Dreams.”

Later, at the end of a lengthy encore that also included “We Are Alive,” “Thunder Road,” “Born to Run,” “Dancing in the Dark” and “Jungleland,” Vedder and Morello emerged side-by-side for “Tenth Avenue Freeze-out” and the rock-and-roll classic “Twist and Shout.”

The sit ins continued the next night when Springsteen returned to Wrigley. Morello took the stage first, sitting in on another version of “Death to My Hometown” and, a few songs later, the Wrecking Ball cut “This Depression.” Then, Vedder made a guest appearance on the area-appropriate Born in the U.S.A. song “My Hometown” as well as “Darkness on the Edge of Town. Later in the set, Morello returned for both “The Ghost of Tom Joad” and “Badlands.” Finally, at the end of the show, both of guests appeared on “American Land.”

In addition to guests, both shows were also dotted with tour debuts and rarities. Of particular note, the E-Street band dusted off the Born in the U.S.A. outtake “None But the Brave.” According to the Springsteen fan magazine Backstreets, it was only the second time the E-Street Band had played the song. Springsteen also called out his guitarist Nils Lofgren, who was born in Chicago in 1951.
