Led Zeppelin ended their heavily 'liked' Facebook countdown Thursday by announcing 'Celebration Day' – a film that will showcase their 2007 reunion concert to the public:

The one night only show, which was set at London's O2 arena, attracted more than 20,000 fans and media from 70 countries, and more than 20 million people applied for the high-demand tickets. The concert featured Zeppelin's three surviving members: singer Robert Plant, bassist John Paul Jones and guitarist Jimmy Page, along with Jason Bonham paying tribute to his father—original drummer John Bonham who passed away in 1980. The charity event celebrated the life of the late Ahmet Ertegun, who signed Zeppelin to Atlantic Records back in 1968. All of the proceeds from the concert went to the Ahmet Ertegun Education Fund.

The five-day series of posts on the band's official Facebook page left some fans anticipating a potential tour, while some caught the drift and remembered back when John Paul Jones hinted the release of the reunion gig back in 2008. For now, scoring a front row seat at the theater this October will be the closest fans will get to seeing Zeppelin live. However, a reunion for the band is likely, with three major premieres for the film planned in London, New York and Los Angeles. Zeppelin has also been announced as one of the recipients of the 2012 John F. Kennedy Center for the Performing Arts honors. Plant, JPJ, and Page are set to receive the honor at the 35th annual celebration scheduled to take place on Dec. 2.

Tickets for 'Celebration Day' will be available to the public on LedZeppelin.com on Sept. 13.
