"The Unreleased Beatles: Music and Film" is a mammoth 350,000-word guide to the incredible wealth of music the Beatles recorded that they did not release, as well as musical footage of the group that hasn't been made commercially available. This revised and expanded ebook edition adds about 30,000 words to the print edition, including coverage of all known material by the group that has gone into circulation since the book's original 2006 release. There is also updated information about the music and film detailed in the original edition, including the appearance of some previously unissued recordings on official releases.
