Led Zeppelin 's surviving members will be in London this Friday to participate in a press event promoting Celebration Day , the film capturing the band's December 2007 reunion concert that will premiere in theaters around the world next month.  Singer Robert Plant , guitarist Jimmy Page and bassist/keyboardist John Paul Jones all will be on hand to meet with the media, and also will attend a screening of the movie.

As recently reported, the film will be screened in about 1,500 cinemas on October 17 after gala premieres are held in several locations, including London, New York City and Los Angeles.  Then, on November 19, Celebration Day will be released to retail in multiple video and audio formats.

Led Zeppelin's one-off reunion set took place at London's O2 Arena, and was the finale of a concert held in memory of the late Atlantic Records founder Ahmet Ertegun .
