It's crazy to think that there could still be any unreleased Beatles recordings out there, but apparently there are. Some of them will finally see the light of day on an upcoming super deluxe edition of the band's 1965 masterpiece Rubber Soul. Producer Giles Martin, son of longtime Beatles collaborator George, worked with engineer Sam Okell on a new stereo mix of Rubber Soul, which will be included alongside the album's original mono mix on the new set. One of those unreleased tracks is "Little Girl," a John Lennon-written tune that has never come out in any form. The reissued version of Rubber Soul is out 10/2 on Apple Corps/Capitol/UMe, and it'll be available in tons of different formats at different price points.
