VIDEO : Krist Novoselic Joins Paul McCartney at His Seattle Show to Perform 'Helter Skelter'

Paul McCartney reunited with his one-time "Sirvana" bandmate Krist Novoselic to perform "Helter Skelter" at his Seattle concert. Paul McCartney's One on One Tour has been packed with surprises since its Fresno launch on April 13th, with the singer performing tracks like the Beatles' "A Hard Day's Night" and "Love Me Do" for the first time as a solo artist. McCartney and Novoselic previously performed together ? along with Dave Grohl and Pat Smear in an outfit playfully dubbed "Sirvana"? at the 12.12.12 benefit, a December 2012 episode of Saturday Night Live and a July 2013 McCartney concert at Seattle's Safeco Park.
