Members of the rock band Led Zeppelin have appeared in court to deny borrowing from another song for their 1971 hit Stairway To Heaven, the BBC reports.
Guitarist Jimmy Page and singer Robert Plant are expected to give evidence at the civil case in Los Angeles.
They are accused of lifting the song’s opening notes from Taurus, a 1967 track by the band Spirit.
Page, 72, and Plant, 67, are being sued by a trust acting for a founding member of Spirit who died in 1997.
The case began with the jury being played various performances of both songs, including part of Led Zeppelin’s recording of Stairway to Heaven.
