At the Reading Festival in England this past week, Pulp's Jarvis Cocker joined the Strokes on stage for a surprise performance of the Cars' classic "Just What I Needed." Even frontman Julian Casablancas seemed shocked by the collaboration, as he mumbled a few (happy!) f-bombs before Cocker ran on stage. And though the two singers' voices may not be the best match in the world, everyone seemed to have a good time – including the audience, whose "Jarvis, Jarvis!" chant can be heard throughout the video. As Casablancas elegantly says at the end of the performance, "Love that man."
