Led Zeppelin today announced the release of Celebration Day, a concert film based on its 2007 performance at London’s O2 Arena, when the band headlined a tribute concert for Atlantic Records founder Ahmet Ertegun. Founding members John Paul Jones, Jimmy Page, and Robert Plant were joined by Jason Bonham, the son of their late drummer John Bonham, to perform 16 songs including “Whole Lotta Love,” “Rock And Roll,” “Kashmir,” and “Stairway To Heaven.” Twenty million people applied for tickets to the show, which was Zeppelin’s first headline performance in 27 years, but only 18,000 seats were sold, via worldwide lottery.
