Who owns Let It Be by The Beatles?

George Martin was the producer of the original sessions. Glyn Johns did some post-production work later in 1969. Neither man's efforts satisfied The Beatles. Phil Spector was brought in to see what he could do, after years of wanting to "produce the Beatles", and did the final post-production work. His overdubs and other touches went against the spirit of the original project, which was to make a "live album" in the studio, and particularly upset Paul McCartney, who hated the work done to "The Long And Winding Road", but it made the album complete... and sellable.
