The Beatles are to release a further album of early out-takes and rare recordings in what is thought to be a bid to give copyright protection to the old material.
The iTunes-only release will contain alternative studio versions and BBC sessions of familiar songs such as From Me To You and I Saw Her Standing There, all made half a century ago.
The album – which stretches to 59 tracks – has not been officially announced but the track listing has appeared on a Norwegian-based Beatles blog. The website which reported the release suggested that the collection, called The Beatles Bootleg Recordings 1963, is an effort to give the material copyright protection. It is reported to be released on Tuesday.
