This anecdote was provided by Ms. Nalini Ramji
In 1947, the Shankar-Jaikishan team was given its first job, composing the music for Barsaat. Their first composition was Main Zindagi Mein Hardam Rota Hi Raha Hun, which required a singer with an extremely wide vocal range. Being new in the field, they were afraid that Rafi, whom they had been told was the only one who could sing it, would refuse to sing for them. When he came to see them, they were very nervous, and said, "Please listen to the tune and sing it as you would like to." Rafi smiled and replied, "You are the composers. I will sing the way you tell me to." From that time, Shankar and Jaikishan quickly climbed the ladder of success, and Rafi became the soul of their music.
