Rolling Stone Ron Wood joined Paul McCartney on stage for "Get Back" during Sir Paul's show at the London 02 Arena last night. The fan footage below is shaky for the first 30 seconds but then straightens out. McCartney debuted several songs that he's never performed in concert before including "Come and Get It," the single he wrote for Badfinger, and "The Word," from The Beatles classic Rubber Soul.

Also check out PM's new website. Last spring we told you that MPL, McCartney's media company, had tapped Hewlett-Packard to create a website that would enable fans to access McCartney's extensive vault of recordings, video, and photographs. Now, the site is up and though it is still a work-in-progress, there's lots of great stuff to check out. We especially like the Rude Studio, which enables you to remix songs from McCartney and Band On the Run.
