Whatever happened to Julian Lennon? After seven years away from the limelight - a time spent getting his life back together after a disillusioning experience with pop stardom' - the son of a beloved rock icon returns to the public eye and ear with his own record label and a new album, Photograph Smile.
Chapman, who was again denied parole last August, shot Lennon in December 1980 outside the Manhattan apartment building where the former Beatle lived. He was sentenced in 1981 to 20 years to life in prison after pleading guilty to second-degree murder.
