An alternative version of Led Zeppelin's epic Stairway To Heaven, never before released, will appear on the latest batch of reissues overseen by guitarist Jimmy Page.
An alternate version of the eight-minute 1971 track, famous for its acoustic guitar intro, much emulated by wannabe Pages in guitar shops across the world, will appear on the October re-release of an expanded version of the band's album, Led Zeppelin IV.
A statement issued by Atlantic, the band's record label, said the re-mastered version of the album will feature "the fabled, alternate version Stairway To Heaven, mixed at the Sunset Sound Studio in Los Angeles which lets fans hear one of the most revered songs of all time as they have never heard it before".
Page, who rescued the mix from the vaults, declined to give further details of the new version. It is expected to shed light on the development of the multi-part song, which is now the subject of a copyright infringement lawsuit from musician Randy California, who argues that the instrumental opening is borrowed from his band Spirit's song Taurus.
The lawsuit seeks a writing credit and a share in future Stairway To Heaven royalties, from sales of the Led Zeppelin IV reissue. The track, subsequently released as a single, is believed to have earned $550m in royalties so far.
