Led Zeppelin founders Robert Plant and Jimmy Page must face trial in a copyright row over the song Stairway to Heaven, a US court has ruled.
A Los Angeles district judge said there were enough similarities between the song and an instrumental by the band Spirit to let a jury decide.
The trial has been scheduled for 10 May.
Stairway to Heaven, released in 1971, is widely seen as one of the greatest rock compositions of all time.
The copyright infringement action has been brought by Michael Skidmore, a trustee for the late Spirit guitarist Randy Wolfe, who played on the same bill as Led Zeppelin in the 1960s, and claims he should be given a writing credit on the track.
Led Zeppelin guitarist Page and lead singer Plant are reputed to have written Stairway to Heaven in a remote cottage in Wales.
