1986 was a year of transition for the former Beatles.         The Lennon estate gave the world two legitimate discs from the archive as an appetizer for years to come.       Julian released his secod disc "The Secret Value of Daydreaming", and  conined his own world tour.      George Harrison took some steps toward a return to the madness that is the music business.      Some musical work was done for the "Shanghai Surprise" film soundtrack, but for the most part, the big story was tales of fights among Madonna and Sean Penn.
