Interviewees, including David Byrnj, William Burroughs and Laurie Anderson, recall what it was like to be young and in love or lust in a more innocent age. The film illustrates its themes with vintage sex education footage and clips featuring teen-idols James Dean, Marlon Brando and Marilyn Monroe.  1988 85mins  Subtitles on 888 What's on at the movies? 316 Next preview C4 Tomorrow Subtitles Film
