Atlantic/Swan Song/Warner MusicAll of the speculation was right: Led Zeppelin is releasing their 2007 reunion concert to fans -- and the news is even better than expected.

After teasing the news for the past week with countdown images on their Facebook page and Twitter, the band on Thursday morning posted the 62-second trailer to Celebration Day, the concert film of their December 10, 2007 one-off reunion concert at London's O2 arena, in memory of the late Atlantic Records founder Ahmet Ertegun. 

Though it was widely believed that Thursday's news would be the concert's release on DVD and CD this November, Zeppelin will first release Celebration Day in movie theaters on 1,500 screens worldwide on October 17, following gala premiers in New York, London, Los Angeles and elsewhere.  Then, just in time for Christmas, Celebration Day will be released November 19 on multiple video and audio formats.

It's a big week for Led Zeppelin, who just Wednesday were announced as one of the 2012 Kennedy Center Honors recipients, joining previous rock honorees Paul McCartney, The Who's Pete Townshend and Roger Daltrey, Bob Dylan, Bruce Springsteen, Elton John, Paul Simon and Brian Wilson.

You can see a list of theaters showing Celebration Day, and buy tickets to the public screenings, starting today at LedZeppelin.com.
