Raj Kapoor made his debut as a director with the film "Aag" in 1948. Its music director Ram Ganguly was assisted by Shankar and Jaikishan. However, during the recording of a song for his new venture "Barsaat", Raj Kapoor had some serious differences with Ram Ganguly and decided to assign its music to Shankar who insisted on taking Jaikishan as his partner. Thus came into existence the new pair of music directors named 'Shankar-Jaikishan' who composed the music for the film.
