The surviving origi-nal members of Led Zeppelin have reunited onstage to promote a concert film of their last performance together in 2007.
Robert Plant, guitarist Jimmy Page and bassist John Paul Jones held a news conference Friday to launch Celebration Day. But although the musicians spoke highly of the film, they refused to commit when asked about a potential future reunion tour.
The film records the band's performance at a concert at London's O2 arena - their first live show together in 27 years.
The movie captures the 1970s hard-rock heroes - joined by Jason Bonham, son of the late original drummer John Bonham - looking relaxed and sounding confident as they powered through hits including Kashmir, Whole Lotta Love and Stairway to Heaven. Celebration Day will be released in theatres around the world Oct. 17 and on DVD Nov. 19.
