Ben Harper and former Pearl Jam drummer Jack Irons made surprise appearances last night (April 13) at the second of two Eddie Vedder solo shows at Los Angeles' Wiltern Theatre.

Harper dueted with Vedder on "No More," their contribution to the recent "Body of War" soundtrack/compilation album, and joined opening act Liam Finn and Eliza Jane Barnes for "Hard Sun."

Irons, who has made sporadic appearances with Pearl Jam since leaving the band in 1998, drummed on "Last Kiss" and, in tandem with Harper on slide guitar, helped Vedder power through a show-closing cover of "All Along the Watchtower."

Earlier in the evening, Finn joined Vedder for a cover of the Hunter and Collectors' "Throw Your Arms Around Me," which Pearl Jam frequently covers live.

Vedder's first solo tour concludes with shows tomorrow and Wednesday in San Diego.
