Dave Grohl brings ten year old guitarist onstage...


 The Foo Fighters gave fans a treat on Friday night when they covered some Metallica with the help of a ten-year-old fan.  Frontman Dave Grohl picked the boy out of the audience and brought him on stage.  He then handed him a guitar, and they performed Metallica's track, Enter Sandman.  Afterward, Grohl gave the boy the instrument as a gift, and jokingly threatened him not to sell it on eBay.  He later wrote on Twitter, "lookout world, next generation of rockers coming soon to an arena near you."
