Bassist Duff McKagan of Guns N’ Roses fame made his debut as a new member of Jane’s Addiction last night (May 5) at a festive, open-air Cinco de Mayo performance at Hollywood’s Bardot.

Among the crowd of about 150 friends and fans were actors Joaquin Phoenix and Danny and Chris Masterson, pro-skater Danny Way and music pals Tom Morello, Matt Sorum, Gilby Clarke and Fishbone’s Chris Dowd, according to the band’s publicist, the Mitch Schneider Organization. Reports of the show appeared on Rollingstone.com and Spin.com.

The band played seven songs, among them the new “Soulmate,” as well as “Stop,” “Mountain Song,” “Had a Dad,” “Whores,” “Ain’t No Right” and “Ocean Size.”

In addition to McKagan (who replaced Eric Avery), the lineup included lead singer Perry Farrell, guitarist Dave Navarro and drummer Stephen Perkins.

McKagan, who continues to work with his own band, Loaded, has been collaborating with Jane’s Addiction since earlier this year. A Cinco de Mayo-themed poster at the club tipped off patrons to the show several days ago.

Jane’s Addiction is writing songs for a new album due in 2011 on Capitol Records. A worldwide concert tour will follow.
