Six unreleased recordings related to The Beatles, including an album of four hitherto unknown songs recorded by John Lennon, rehearsals of "Sargent Pepper's Lonely Hearts Club Band" and a production by George Harrison with a version of "While My Guitar Gently Weeps" featuring Jimmy Page on guitar, are auctioned by the online betting house Gotta Have Rock and Roll at a starting price of $300,000.   The tapes were until now in the possession of Derek Taylor, press officer of the popular band, who confirmed that they planned to be released through Zapple, an Apple subsidiary dedicated to experimental projects, but that they were finally archived, according to European newspapers.   The most striking of these productions is an unreleased album by John Lennon titled "One From The Nursery" recorded in 1969 at his home in Tittenhurst Park and in which Kyoko Cox, Yoko Ono's daughter, participates.   The album contains 45 minutes of four unreleased songs, of which only the title of two of them is known: "John, I Love You" and "I Wish You Were My Father."   Another tape consists of rehearsals by "Sargent Pepper's Lonely Hearts Club Band" recorded between late 1966 and early 1967, which also includes animal sounds used in the final recording of the revolutionary album.   A third tape is about a collaboration by George Harrison with the Bonzo Dog Doo-Dah Band, a group made up of British art students related to Monty Python, where you can hear a version of "While My Guitar Gently Weeps" in which Future Led Zeppelin guitarist Jimmy Page participates.   @fotoW In the package there is also another album by Harrison with this group that contains about 16 songs, an interview with Lennon where he talks about his relationship with Yoko Ono and reveals intimate details about his life, and a therapeutic session of Yoko herself with Arthur Janov , creator of the methodology known as "primal scream".   The auction clarified that the sale consists only of the material but not of its respective copyrights, so its eventual owner will only be able to listen to it privately, which is why it is presumed that the tapes will remain unreleased for the general public.
