The band has been counting down to an official announcement, due Thursday, regarding the release of their 2007 London show on DVD and CD.

Rumor has it the package will be available November 22 to coincide with the U.S. Thanksgiving Day holiday.

On Wednesday, the band posted the studio version of Led Zeppelin III’s “Celebration Day,” to tease the news.

Cineplex has posted its plans to premiere the new package, “Led Zeppelin: Celebration Day,” in its theatres on October 17.

Here’s the Cineplex info:

On December 10, 2007, Led Zeppelin took the stage at London’s O2 Arena to headline a tribute concert for dear friend and Atlantic Records founder Ahmet Ertegun. What followed was a two--- hour---plus tour de force of the band’s signature blues---infused rock ’n’ roll that instantly became part of the legend of Led Zeppelin.

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 from their celebrated catalogue including landmark tracks “Whole Lotta Love,” “Rock And Roll,” “Kashmir,” and “Stairway To Heaven.”

Although 20 million people applied for tickets, the band’s first headline show in 27 years was seen only by the 18,000 ticket holders who were fortunate enough to have secured seats through the worldwide lottery.

Now, for the first time, fans in over 40 territories worldwide will be able to get a front row seat to experience this historic event in glorious high definition and incredible surround sound. Experience it on the big screen for a strictly limited period only.

Cineplex lists three dates for the screening on their website: October 17, 19 and 25.
