While the countdown on Led Zeppelin's Facebook page is still stuck on No. 1, there are reports that the long-rumored release of the band's 2007 show at the O2 Arena in London will take place first in theaters next month, and then on DVD in November. It seems their big announcement may have leaked. 

A listing at Cineplex.com shows 'Led Zeppelin: Celebration Day' coming to theaters in "over 40 territories worldwide" on Oct. 17. While it's not clear where those territories will be, it's clear that the run is a limited engagement, perhaps one night only. The synopsis makes clear that it is indeed the 2007 show in honor of Atlantic Records founder Ahmet Ertegun that will be screened in high definition.

Yesterday the British newspaper the Sun may have scooped the band on the DVD and Blu-ray release date, reporting that both will be available on Nov. 22. While it's not certain the Facebook countdown is leading to an announcement of how fans unable to score a ticket to the show at the O2 Arena can see the concert, it's worth pointing out that Day 0 (Sept. 13) marks the fifth anniversary of when the band announced the show.

The 16 song set included many of the rock legend's most well-known tracks, like 'Kashmir,' 'Stairway to Heaven' and 'Rock and Roll.' It was their first headlining show in 27 years, and included the three surviving members, with Jason Bonham replacing the late John Bonham.
