Paul McCartney invited Nirvana bass player Krist Novoselic to join him onstage during a show in Seattle.
At last night's (April 17th) show the Beatles icon kept fans on their toes, bringing the One On One tour to Seattle.
Nirvana bass player Krist Novoselic emerged for a performance of 'Helter Skelter', the first time the two have worked together since the 2012 track 'Cut Me Some Slack' (which features Dave Grohl on drums).
One On One kicked off in Fresno, and is currently working its way across the United States.
