Pearl Jam has never forgotten Mother Love Bone, the short-lived Seattle band that produced two of PJ’s founding members, guitarist Stone Gossard and bassist Jeff Ament.

Pearl Jam recorded ‘Crown of Thorns’ on Oct. 22, 2000, during a concert at the MGM Grand in Las Vegas.

In the CD booklet for the soundtrack, ‘PJ20′ director Cameron Crowe says, “I asked [Pearl Jam singer Eddie] Vedder about Andrew Wood, the late singer-songwriter of Mother Love Bone, whose passing left the place that Vedder would later fill. Though Vedder chose not to name the song, he did say there was one Wood composition he would be honored to sing ‘one day.’ He declined to say more.”

The ‘PJ20′ soundtrack is due Sept. 20, the same day the documentary hits select theaters in the United States and Canada.

‘PJ20′ will begin a one-week theater run in key markets starting Sept. 23.
