The Beatles plan to release a new collection of the band's BBC sessions, including commercially unreleased recordings and studio chatter.
The CD and vinyl release planned for November will be a follow-up to the wildly successful "Live at the BBC" album released in 1994.
The new compilation comes from BBC radio broadcasts in 1963 and 1964, when the band was making dozens of appearances in BBC studios.
Most of the recordings have a live feel and capture the Beatles in a relaxed, informal setting. In addition to early Lennon-McCartney compositions, they play a number of Chuck Berry songs and other works by rock pioneers.
The new release will include different versions of some of the songs from the first Live at the BBC album.
A re-mastered version of the earlier album will also be released in November. It topped record charts on its release, selling more than 5 million copies worldwide in its first six weeks.
