Manthan is a 1976 Hindi film made by Shyam Benegal, based on the story of the pioneering milk cooperative movement of Verghese Kurien (the Father of the White Revolution in India) written jointly by him and Vijay Tendulkar. It is set amidst the backdrop of the White Revolution of India (Operation Flood) which started in 1970, ushering an era of plenty, from a measly amount of milk production and distribution. Aside from the great measurable success that this project was, it also demonstrated the power of "collective might".
The title song (whose lyrics go Mero gaam kathaparey) was sung by Preeti Sagar. She won the Filmfare Award for Best Female Playback Singer for that year. The song was later used as the soundtrack for the television commercial for Amul.
