(FILES) US pop idol Michael Jackson waves to more than 100 reporters and photographers while entering a press conference room at a Tokyo hotel July 27, 2009. A retired California highway patrolman has stumbled into possession of a trove of unreleased Michael Jackson songs -- which the world may never have a chance to hear. Gregg Musgrove, now a stay-at-home dad, procured the tapes after an associate purchased a storage unit in the city of Van Nuys that contained the recordings, according to the Hollywood Reporter.
