Former Metallica bassist Jason Newsted is recovering after he was knocked offstage by an overzealous fan during a gig in New York on Tuesday (21May13). The 50 year old was performing a rendition of Whiplash at the Highline Ballroom with his solo band Newsted when a concertgoer hopped onstage and bumped into the musician during an attempt to crowd surf, sending them both tumbling into the audience. The overexcited fan was removed by security, while Newsted was helped to his feet. Joking to the crowd, he said, "You know, no matter how many shows I've done, that just happened for the first time. I trust my brothers here to take care of it. Anyone get a good look at that motherf**ker? Don't kill him - just bruise him up a bit." Although the rocker, who has suffered with severe shoulder and back pain for years, was visibly disoriented, he appeared to have escaped major injury, according to MetalInsider.net.
