The legions of Led Zeppelin fans that weren't lucky enough to get into the O2 Arena in London on Monday night got some good news and some bad news today.

The good: A third-party vendor admitted today that it, not Zeppelin or its label Warner Music Group, was responsible for the forcible takedown from YouTube of dozens of videos from the reunion show. The takedown notices were automated, Grayzone said yesterday, and videos have begun to reappear on the video-sharing site, allowing fans around the world to watch clips from what has been widely hailed as a stellar performance.

"Grayzone regrets that it erroneously issued takedown notices to YouTube regarding footage of Led Zeppelin's Dec. 10 concert," company president Dorothy Sherman said in a statement. "The error is ours alone. We acted without authorization from the band or Warner Music Group. Unfortunately, an automated system mistakenly attributed the removal of the content to a copyright claim by Warner Music Group. That was inaccurate. We have informed YouTube of the error and we regret any inconvenience this may have caused."

The bad: Zeppelin frontman Robert Plant announced plans today to tour in 2008 with Alison Krauss, with whom he recorded the acclaimed album Raising Sand. Plant and Krauss are set to tour Britain and Europe in May, and the US in the middle of the year, which leaves a much-rumored Zeppelin reunion tour in doubt.

In the weeks leading up to Zeppelin's reunion show as a tribute to Atlantic Records founder Ahmet Ertegun earlier this week, rumors were swirling that the legendary rock band was set to turn the reunion into a full-blown tour, with a slot at Bonnaroo in June already reported. With Plant, Jimmy Page, John Paul Jones, and late Zeppelin drummer John Bonham's son Jason drawing widespread praise for their performance Monday, cries grew even louder.

But Plant's announcement likely quashes those rumors, although there would still be plenty of room in his schedule for one-off dates, as has also been rumored. Shows at Madison Square Garden and at the UK's Glastonbury festival have also been speculated as possibilities.
