This year, headliners for Neil Young's 21st annual Bridge School Benefit concert - which raises money for a children's speech impediment program co-founded by his wife, Pegi - will include Metallica, Jerry Lee Lewis, Eddie Vedder with Flea and Jack Irons, Tom Waits with Kronos Quartet, John Mayer, Tegan & Sara and Regina Spektor. Tickets for the event, which happens Oct . 27-28, go on sale this Sunday through Live Nation. Young himself will host and perform, as he has since its formation.
