The duo performed “I Saw Her Standing There”
Steven Van Zandt surprised his fans during a show in London when he invited Paul McCartney to join him on stage.
The show was the guitarist's first with his band Little Steven And The Disciples Of Soul in 25 years.
When calling up McCartney, Van Zandt tells the audience that the duo has unfinished business, referring to a 2012 performance they gave at Hard Rock Calling that was interrupted after the power went out due to the city's curfew.
