It was words and not music as singer Robert Plant, guitarist Jimmy Page and bassist John Paul Jones held a news conference Friday to launch "Celebration Day."
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" is released in theaters around the world Oct. 17 and on DVD Nov. 19.
