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.
After a self-imposed retirement from 1976 to 1980, Lennon reemerged with a comeback album, Double Fantasy, which would win the 1981 Grammy Award for Album of the Year. Less than one month after the release of the album, Lennon was murdered in New York City on 8 December 1980.
