This kitschy teenage love story was a box-office hit, combining '60s pop         sensibility, great music (including the famous love song "Hum tum ek kamre       mein band ho," sung by Shailendra Singh and Lata Mangeshkar), and shades of      Romeo & Juliet, but with a happy ending. Rishi Kapoor, Dimple Kapadia,   Premnath, and Durga Khote star. In Hindi with English subtitles.               Raj Kapoor---India---1973---168 mins.
