On Saturday (September 8), LED ZEPPELIN posted a cryptic graphic on its Facebook page that is believed to be releated to the imminent announcement of the DVD/CD release of the band's 2007 reunion for the Ahmet Ertegun tribute concert at London's O2 Arena.An image with the number "Five" — in ZEPPELIN logo font — has sent the rumor mill into overdrive as fans speculate about its meaning. One clue may have been offered by LED ZEPPELIN guitarist Jimmy Page's manager, Peter Mensch, who alluded to the upcoming release in a tweet on Saturday, writing, "it's almost here. I've seen it and heard it. almost 5 years to the day." Mensch was more specific in a July 9 tweet when he wrote, "today, [producer/engineer Alan] Moulder continues with his stellar mixing of the O2 show. it's been 5 years coming and it's almost here." The new LED ZEPPELIN set is rumored to consist of a double DVD accompanied by two CDs and is expected to be released in November. An estimated nine million people applied for the 18,000 tickets to the O2 Arena show, which featured Jason Bonham taking his late father's place behind the drum kit. In its review of the concert, NME.com wrote that LED ZEPPELIN singer Robert Plant spoke little during the show, but when he did, it was mostly to pay tribute to Ertegun, who he said after first encore "Whole Lotta Love", "ran the best label in the world" in Atlantic Records. Speaking to the Los Angeles radio station KLOS in December 2010, Jason stated about the prospect of the concert being released on DVD, "Nothing is official, as yet. I only know that because Robert had said that he'd watched it. I really do hope that it eventually will see the light of day. It's just nice to know that Robert had seen it, so I knew something, but it was nice that he rang up and said, 'Wow, it sounded great.' Fingers crossed, everybody… fingers crossed." In an interview with U.K.'s Telegraph.co.uk, Plant was asked about ZEPPELIN's 2007 reunion concert. "I really had a wonderful time," said Plant. "It was the best LED ZEPPELIN gig since 1975." When asked if he would do it again, Plant replied, "I don't think so. You've got to have a lot in common with the people you're working with at this time in your life. Everything has to move on and forward, in all relationships. "I know that bands that haven't put out a record for 10 years are playing to 20,000 people a night. But that's not the achievement. The achievement is to knock yourself out. It's a very selfish thing. The tail must never wag the dog." A few months back, radio personality and "That Metal Show" co-host Eddie Trunk tweeted, "Heard from a very reliable source backstage at AEROSMITH show that there will be some sort of LED ZEPPELIN activity around Christmas."
