A lost Led Zeppelin BBC radio session has been recovered from a fan's recording.
In 1969 the legendary rock band played a special set which was broadcast as part of Alexis Korner's Rhythm and Blues programme on BBC world service radio.
It had been thought that the session, which included the only known recording of the track Sunshine Woman, had been lost due to BBC bosses' now abandoned policy of wiping archive tapes for reuse.
However, a fan taped the session recording from an AM radio in Europe, and it has now been restored with help from the band's guitarist Jimmy Page.
The recording session will now be released in September (16) as part of an album titled The Complete BBC Sessions, which will also feature other rare recordings the group made for the BBC.
Eight of the songs on the record are previously unreleased, including Sunshine Woman and two others from the previously lost 1969 recording.
Speaking about the importance he placed on the group's recordings for the BBC in 2008 Jimmy told Britain's 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."
Formed in 1968, Led Zeppelin went on to become one of the biggest rock bands of the 1970s with hits like Whole Lotta Love, Black Dog and Stairway To Heaven.
A dispute over the origin of the latter song recently caused Jimmy and bandmate Robert Plant to be embroiled in a bitter court battle after facing a lawsuit which accused them of plagiarising parts of the track from a song called Taurus by the band Spirit.
However last month (Jun16) a U.S. federal jury rejected the lawsuit after deciding there was not enough evidence to support the claims made by lawyers on behalf of the estate of the late Spirit songwriter/guitarist Randy Wolfe.
