Andaz (1971)

A widow and a widower, each raising a child alone, and the families who will not let them marry. Shammi Kapoor, Hema Malini and Rajesh Khanna lead. It was Ramesh Sippy's first film as director, four years before Sholay, and Kishore Kumar's "Zindagi Ek Safar Hai Suhana" comes from it. The Internet Archive copy was uploaded with its format details disguised, so playback is withheld here; the entry stays listed and the Archive's own page remains reachable.
