Dosti (1964)

A boy who cannot walk and a boy who cannot see make a living together on the streets of Bombay, one playing the harmonica and the other singing. It won the Filmfare award for Best Film, and Laxmikant-Pyarelal's score — their breakthrough — carries "Chahunga Main Tujhe", sung by Mohammed Rafi. The upload it came from had its format details disguised by the uploader, which is a fact about that upload and not about the film.
