A fan-made recording of a "lost" 1969 Led Zeppelin session which was wiped from BBC archives has been recovered.
The band's guitarist Jimmy Page has helped to restore the 47-year-old recording, which was taped from an AM radio in Europe when it was first broadcast.
Rock music fans will be able to hear the "lost session" on new compilation album The Complete BBC Sessions, available from September 16.
Led Zeppelin recorded the session in 1969 in London for the BBC World Service as part of Alexis Korner's Rhythm and Blues programme.
Among the three tracks from the session is a performance of Sunshine Woman - the only recording of the song in existence.
The new release is a follow-up to 1997´s BBC Sessions compilation album, a set of live recordings from the band's BBC radio appearances between 1969 and 1971.
The updated version, newly remastered with the help of Jimmy, has been expanded to include eight unreleased BBC recordings.
The collection includes the first broadcast of Stairway To Heaven, recorded at the BBC Paris Cinema in London on April 1 1971.
Other songs on the album include I Can't Quit You Baby and You Shook Me, as well as unreleased versions of Communication Breakdown and What Is And What Should Never Be.
In 2008, Jimmy told Guitar World: "The BBC Sessions show in graphic detail just how organic the group was.
"Led Zeppelin was a band that would change things around substantially each time it played ... We were becoming tighter and tighter, to the point of telepathy."
