The Web has been rife with speculation about why footage from the historic Led Zeppelin reunion concert has been removed from YouTube.

Although Warner Music Group does have a licensing deal in place with YouTube that would allow fans to post WMG-copyrighted material, sources close to the situation say that Led Zeppelin owns the rights to this week's concert, and that the band's management requested the removal of any clips of the event.

Fans looking to stream the clips after they were removed were greeted with a notification that the content was removed at WMG's request. WMG, and most other labels, will often take on the task of content removal requests for content controlled by their artists on their behalf when asked.
